▼ Collective motion is a widespread phenomenon in nature where individuals actively propel themselves, gather together and move as a group. Some examples of collective motion are bird flocks, fish schools, bacteria swarms, cell clusters, and crowds of people. Many models seek to understand the effects of activity in collective systems including things such as environmental disorder, density, and interaction details primarily at infinite size limits and with uniform populations. In this dissertation I investigate the effects of finite sizes and behavioral heterogeneity as it exists in nature. Behavioral heterogeneity can originate from several different sources. Mixed populations of individuals can have inherently different behaviors such as mutant bacteria, injured fish, or agents that prefer individualistic behavior over coordinated motion. Alternatively, agents may modify their own behavior based on some local environmental dependency, such as local substrate, or density.In cases such as mutant cheaters in bacteria or malfunctioning drones in swarms, mixed populations of behaviorally heterogeneous agents can be modelled as arising in the form of aligning and non-aligning agents. When this kind of heterogeneity is introduced, there is a critical carrying capacity of non-aligners above which the system is unable to form a cohesive ordered group. However, if the cohesion of the group is relaxed to allow for fracture, the system will actively sort out non-aligning agents the system will exist at a critical non-aligner fraction. A similar heterogeneity could result in a mixture of high and low noise individuals. In this case there is also a critical carry capacity beyond which the system is unable to reach an ordered state, however the nature of this transition depends on the model details. Agents which are part of an ordered collective may vary their behavior as the group changes environments such as a flock of birds flying into a cloud. Using a unique model of a flock where the group behaves as a rigid disk reveals interesting behaviors as the system crosses a boundary between interfaces. The collective rotates and reorients or becomes stuck on the boundary as it crosses. I also investigate the effects of variable behavior depending on local density, and find that a frustration driven transient rotational phase arises in clusters where agents with low local density move faster than those with high local density as in cell clusters. All together I have shown that behavioral heterogeneity in collective motion can lead to unique phases and behaviors that are not seen in their homogeneous counterparts.

▼ Copper sulfides with different copper concentration exist in mineral form ranging from CuS to Cu₂S. Among these, chalcosite Cu₂S, and digenite Cu_1.8S were the subject of extensive research for decades mainly because of their use as the absorber in photovoltaic cells. Yet, their electronic structure is poorly understood because their crystal structure is complex. Most of the results published so far report the semiconducting nature of these compounds with the energy band gap being in the range of 0.84 to 1.9 eV. The crystal structure consists of a close-packed lattice of S with mobile Cu occupying various types of interstitial sites with a statistical distribution depending on temperature. In this thesis we present the first computational study of their electronic band structure. Initially, we investigated the simpler antifluorite structure. Both local density approximation (LDA) and self-consistent quasiparticle GW calculations with the full-potential linearized muffin-tin orbital method give a semimetallic band structure. Inspection of the nature of the bands shows that the lowest conduction band is mainly Cu-s-like except right near the center of the Brillouin zone where a Cu-s-like state lies about 1 eV below the valence band maximum. Significantly, in GW calculations, this state shifts up by several 0.1 eV but not sufficiently to open a gap. A random distortion of the Cu atoms from the perfect antifluorite positions is found to break the degeneracy of the d state at the Gamma-point and thus opens up a small gap of about 0.1 eV in LDA. As our next step we constructed supercell models for the cubic and hexagonal phases with the Cu positions determined by a weighted random number generator. The low temperature monoclinic phase was also studied. The computed total energies of these structures follow the same order as the reported phases with increasing temperatures. All these models gave similar small band gaps of order 0.1 – 0.2 eV. However, their conduction band is now mainly s-like and addition of an expected Cu-s level shift opens the gap to about 0.5 eV. Some simpler hexagonal model structures gave slightly larger band gap but were found to be unrealistic. The optical absorption data all show a strong intraband absorption with a minimum in absorption at about 1 eV. Our calculations suggest a significantly lower gap of order 0.5 eV with low absorption cross section, the true nature of which is masked by the free carrier absorption. As part of our study of the related Cu-compounds, we analyzed the quasiparticle effects beyond LDA obtained from a GW calculation on the effective masses and Kohn-Luttinger hamiltonian parameters for CuBr.

▼ The fundamental aim in our investigation of the interaction of a polymer film with a nanoparticle is the extraction of information on the dynamics of the liquid using a single tracking particle. In this work two theoretical methods were used: one passive, where the motion of the particle measures the dynamics of the liquid, one active, where perturbations in the system are introduced through the particle. In the first part of this investigation a thin polymeric film on a substrate is studied using molecular dynamics simulations. The polymer is modeled via a 'bead spring' model. The particle is spheric and non structured and is able to interact with the monomers via a Lennard Jones potential. The system is micro-canonical and simulations were performed for average temperatures between the glass transition temperature of the film and its dewetting temperature. It is shown that the stability of the nanoparticle on the polymer film in the absence of gravity depends strongly on the form of the chosen interaction potential between nanoparticle and polymer. The relative position of the tracking particle to the liquid vapor interface of the polymer film shows the glass transition of the latter. The velocity correlation function and the mean square displacement of the particle has shown that it is caged when the temperature is close to the glass transition temperature. The analysis of the dynamics at long times shows the coupling of the nanoparticle to the center of mass of the polymer chains. The use of the Stokes-Einstein formula, which relates the diffusion coefficient to the viscosity, permits to use the nanoparticle as a probe for the determination of the bulk viscosity of the melt, the so called 'microrheology'. It is shown that for low frequencies the result obtained using microrheology coincides with the results of the Rouse model applied to the polymer dynamics. In the second part of this investigation the equations of Linear Hydrodynamics are solved for a nanoparticle oscillating above the film. It is shown that compressible liquids have mechanical response to external perturbations induced with the nanoparticle. These solutions show strong velocity and pressure profiles of the liquid near the interface, as well as a mechanical response of the liquid-vapor interface. The results obtained with this calculations can be employed for the interpretation of experimental results of non contact AFM microscopy

▼ Strongly correlated low-dimensional quantum spin models provide a well-established frame- work to study magnetic properties of insulators, and are of great theoretical interest and experimental relevance in condensed-matter physics. In this thesis, I use quantum Monte Carlo methods to numerically study quantum critical behavior in low-dimensional quantum spin models and wavefunctions. First, I study spinons &ndash emergent spin-1/2 bosonic excitations &ndash at certain one- and two-dimensional quantum phase transitions (QPTs) in spin models, by characterizing their size and confinement length quantitatively. In particular, I focus on the QPT from an antiferromagnetic (AFM) phase into a valence-bond solid (VBS) phase, which is an example of a violation of the standard Landau-Ginzburg-Wilson paradigm for phase transitions. This transition in two dimensions (2D) is instead likely described by a novel theory called "deconfined quantum criticality" (DQC). According to the theory, spinons should be deconfined. The degree of deconfinement is quantified in my calculations. Second, I present a comprehensive study of so-called short-bond resonating-valence-bond (RVB) spin liquids in 2D, which have been suggested as a good starting point for understanding the spin physics of high-temperature cuprates. I find that these RVB states can also be classified as quantum-critical VBS states, which indicates that RVB is less disordered than expected. This work suggests a possible mapping from the quantum RVB states to classical dimer models via a classical continuum field theory – the height model. This map explicitly bridges well-established classical results to future quantum studies. Third, I consider 1D amplitude product (AP) states, which are generalized versions of RVB states, with different wavefunction weightings of bonds according to their lengths. AP states constitute a good ansatz for certain Hamiltonians and are of broad interest in quantum magnetism. I study phase transitions from AFM-VBS phases in AP states by tuning their amplitudes, and obtain continuously varying critical exponents. In addition, I classify the 1D AP states through entanglement entropy calculations of the central charge in (1+1)D conformal field theory. This new classification could serve as guide for AP states as trial wavefunctions to search for ground states of corresponding quantum spin models.

▼ In this dissertation, Large Eddy Simulations (LES) are used to model the coupled turbulence-reactive tracer dynamics within the upper mixed layer of the ocean. Prior work has shown that LES works well over the spatial and time scales relevant to both turbulence and reactive biogeochemistry. Additionally, the code intended for use is able to carry an arbitrary number of tracer equations, allowing for easy expansion of the species reactions. Research in this dissertation includes a study of 15 idealized non-reactive tracers within an evolving large-scale temperature front in order determine and understand the fundamental dynamics underlying turbulence-tracer interaction in the absence of reactions. The focus of this study, in particular, was on understanding the evolution of biogeochemically-relevant, non-reactive tracers in the presence of both large (~5 km) submesoscale eddies and smallscale (~100 m) wave-driven Langmuir turbulence. The 15 tracers studied have different initial, boundary, and source conditions and significant differences are seen in their distributions depending on these conditions. Differences are also seen between regions where submesoscale eddies and small-scale Langmuir turbulence are both present, and in regions with only Langmuir turbulence. A second study focuses on the examination of Langmuir turbulence effects on upper ocean carbonate chemistry. Langmuir mixing time scales are similar to those of chemical reactions, resulting in potentially strong tracer-flow coupling effects. The strength of the Langmuir turbulence is varied, from no wave-driven turbulence (i.e., only shear-driven turbulence), to Langmuir turbulence that is much stronger than that found in typical upper ocean conditions. Three different carbonate chemistry models are also used in this study: time-dependent chemistry, equilibrium chemistry, and no-chemistry (i.e., non-reactive tracers). The third and final study described in this dissertation details the development of a reduced-order biogeochemical model with 17 state equations that can accurately reproduce the Bermuda Atlantic Time-series Study (BATS) ecosystem behavior, but that can also be integrated within high-resolution LES.

▼ This research focuses on the computational modeling of fluctuations, interactions, phase behavior and structural characteristics of multicomponent polymeric systems. The role of fluctuations is studied in the context of block copolymer melts and polymer blends stabilized using copolymers exhibiting different sequence architectures. The relationship between interparticle interactions and structural characteristics of the aggregates formed in particle-polymer solutions is examined for charged nanoparticle-polymer and charged dendrimer-polyelectrolyte system. A hybrid Monte Carlo and self consistent field theory approach employed in single chain in mean field simulations (SCMF) is utilized in order to achieve the equilibrium morphologies/aggregates in such polymeric systems. We examine the effect of composition fluctuations on the phase behavior of polydisperse block copolymer melts quantified in terms of fluctuation-induced shift in the order-disorder transition temperature from the corresponding mean-field predictions. Fluctuation effects can also play an important role in stabilizing bicontinuous microemulsions phases. To study this effect, we examine polymer blend systems compatibilized by a copolymer having different sequence architectures such as monodisperse and polydisperse block copolymer, and gradient copolymer. We systematically assess the efficiency of such system in forming bicontinuous microemulsions phases. We also study the effect of sequence architecture on the phase behavior of gradient copolymer solutions. We extend above framework to account for electrostatic effects arising from charged polymers and dendrimers. Using such a framework, we characterize the clusters formed due to electrostatic binding between oppositely charged dendrimers and polyelectrolytes. Our results indicate that, the binding is maximum when the charge on dendrimers is balanced by the charge on the polyelectrolytes. We extend the above study to probe the phase behavior of charged nanoparticles suspended in polymer solutions. We examine the influence of polymer concentration, particle volume fraction, and particle charge on the structure and size of clusters. We also examine the influence of multibody effects on the resulting structure of nanoparticle clusters. The charged nanoparticle-polymer solution is seen to exhibit significant multibody effects and the effective two-body interparticle potentials are seen to be a function of nanoparticle density.

▼ Soft materials have attracted considerable interest in recent years for predicting the characteristics of phase separation and self-assembly in nanoscale structures. A popular method for demonstrating and simulating the dynamic behaviour of particles (e.g. particle tracking) and to consider effects of simulation parameters is cell dynamic simulation (CDS). This is a cellular computerisation technique that can be used to investigate different aspects of morphological topographies of soft material systems. The acquisition of quantitative data from particles is a critical requirement in order to obtain a better understanding and of characterising their dynamic behaviour. To achieve this objective particle tracking methods considering quantitative data and focusing on different properties and components of particles is essential. Despite the availability of various types of particle tracking used in experimental work, there is no method available to consider uniform computational data. In order to achieve accurate and efficient computational results for cell dynamic simulation method and particle tracking, two factors are essential: computing/calculating time-scale and simulation system size. Consequently, finding available computing algorithms and resources such as sequential algorithm for implementing a complex technique and achieving precise results is critical and rather expensive. Therefore, it is highly desirable to consider a parallel algorithm and programming model to solve time-consuming and massive computational processing issues. Hence, the gaps between the experimental and computational works and solving time consuming for expensive computational calculations need to be filled in order to investigate a uniform computational technique for particle tracking and significant enhancements in speed and execution times. The work presented in this thesis details a new particle tracking method for integrating diblock copolymers in the form of spheres with a shear flow and a novel designed GPU-based parallel acceleration approach to cell dynamic simulation (CDS). In addition, the evaluation of parallel models and architectures (CPUs and GPUs) utilising the mixtures of application program interface, OpenMP and programming model, CUDA were developed. Finally, this study presents the performance enhancements achieved with GPU-CUDA of approximately ~2 times faster than multi-threading implementation and 13~14 times quicker than optimised sequential processing for the CDS computations/workloads respectively.

▼ The dynamics of Saturn's magnetosphere are driven internally by the planet's strong magnetic field, rapid rotation rate, and inner-magnetosphere plasma source, and externally by the solar wind. We use a multifluid magnetohydrodynamic simulation of Saturn's magnetosphere to investigate the production and transport of new plasma, the dynamics of Saturn's magnetotail, and response to seasonal variation. Saturn's closely aligned magnetic dipole and rotational axes are inclined 26.7° relative to the plane of its orbit. As a result, the magnetospheric morphology is strongly influenced by the solar wind; the plasma sheet is deformed into a "basin" at solstice, with decreasing curvature as the planet approaches equinox. Internally, new water group plasma is produced by ionization of Saturn's distributed neutral cloud, while charge-exchange collisions between magnetospheric ions and neutrals result in a loss of momentum from the plasma. New plasma is accelerated towards corotation by the magnetic field, while centrifugal stresses cause it to move radially outward. In order to prevent runaway inflation of the magnetosphere, this plasma must eventually escape, either through the flanks or down the magnetotail. The Saturn multifluid model features three ion species (protons, water group ions, and a heavy tracer), allowing us to track the dynamics of each ion species, as well as the evolution of the electron pressure. We have modified the simulation to include neutral cloud interactions, specifically photoionization, electron impact ionization, and symmetric charge exchange, enabling simulation of mass-loading as a function of local plasma variables. Our 3D multifluid global simulation provides global context for in-situ observations, which, while valuable, only provide data from a single spatial location at a given time. We use this model to study the production and outflow of plasma in the inner magnetosphere, as well as the characteristics of inward-moving outer-magnetosphere injection fingers. We also investigate the impact of seasonal changes on the global magnetospheric configuration and dynamics, as well as the plasma production and transport processes in the inner and middle magnetosphere. Finally, we investigate the evolution of plasmoids and their possible role in removing inner magnetosphere plasma. We validate our results using data from the Cassini Plasma Spectrometer and Magnetometer instruments (CAPS and MAG). Advisors/Committee Members: Paty, Carol S. (advisor), Dufek, Josef D.

Physics

Understanding the “incomprehensible” world of materials is the biggest challenge to the materials science community. To access the properties of the materials and to utilize them for positive changes in the world are of great interest. Often scientists use approximate theories to get legitimate answers to the problems. Density functional theory (DFT) has emerged as one of the successful and powerful predictive methods in this regard. The accuracy of DFT relies on the approximate form of the exchange-correlation (EXC) functional. The most complicated form of this functional can be as accurate as more complicated and computationally robust method like Quantum Monte Carlo (QMC), Random Phase Approximation (RPA). Two newest meta-GGAs, SCAN and SCAN+rVV10 are among those functionals. Instantaneous charge fluctuation between any two objects gives rise to the van der Waals (vdW) interactions (often termed as dispersion interactions). It is a purely correlation effect of the interacting electrons and thus non-local in nature. Despite its small magnitude it plays a very important role in many systems such as weakly bound rare-gas dimers, molecular crystals, and molecule-surface interaction. The traditional semi-local functionals can not describe the non-local of vdW interactions; only short- and intermediate-range of the vdW are accounted for in these functionals. In this thesis we investigate the effect of the weak vdW interactions in surface properties, rare-gas dimers and how it can be captured seamlessly within the semi-local density functional approximation. We have used summed-up vdW series within the spherical-shell approximation to develop a new vdW correction to the meta-GGA-MS2 functional. This method has been utilized to calculate binding energy and equilibrium binding distance of different homo- and hetero-dimers and we found that this method systematically improves the MGGA-MS2 results with a very good agreement with the experimental data. The binding energy curves are plotted using this MGGA-MS2, MGGA-MS2-vdW and two other popular vdW-corrected functionals PBE-D2, vdW-DF2. From these plots it is clear that our summed-up vdW series captures the long-range part of the binding energy curve via C6, C8, and, C10 coefficients. The clean metallic surface properties such as surface energy, work functions are important and often play a crucial role in many catalytic reactions. The weak dispersion interactions present between the surfaces has significant effect on these properties. We used LDA, PBE, PBSEsol, SCAN and SCAN+rVV10 to compute the clean metallic surface properties. The SCAN+rVV10 seamlessly captures different ranges of the vdW interactions at the surface and predicts very accurate values of surface energy ( ) , and work function (𝞥) and inter-layer relaxations (𝞭%). Our conclusion is adding non-local vdW correction to a good semi-local density functional such as SCAN is necessary in order to predict the weak attractive vdW forces at the metallic surface. The SCAN+rVV10 has also been employed to…

A Frutalina é uma proteína tetramérica ligante de carboidratos obtida através de sementes Artocarpus incisa. Os interesses biomédicos da Frutalina estão em sua alta afnidade de ligação por carboidratos presentes em algumas células tumorais específicas. Até agora, nenhum estudo teórico computacional foi realizado para investigar as características de ligação da Frutalina. Neste trabalho, através de um estudo multidisciplinar, investigamos as propriedades de ligação e óticas da Frutalina com carboidratos. Utilizamos um modelo-corte teórico, considerando apenas o sítio ativo de ligação com o carboidrato construído com o auxílio de docking molecular e mecânica molecular clássica. As energias de ligação são obtidas através de uma abordagem quântica ab initio all electron, dentro da Teoria do Funcional da Densidade (DFT), no espaço recíproco que combina o método Projector Augmented Waves (PAW) e a dinâmica molecular de Car-Parrinello (CP). Uma metodologia Hartree-Fock (HF) semi-empírica é utilizada para obter as propriedades óticas. A investigação deste problema muito complexo pode ser dividido em seis etapas principais: a) estudamos as propriedades estruturais da proteína para avaliar a sua mobilidade e escolhemos um conjunto de dados de raios-X para descrever o sistema; b) aplicamos a técnica de docking molecular para ligar quatro carboidratos ( alfa-metil-D-galactose, beta-D-galactose, O1-metil-manose e alfa-metil-D-glucopiranose) na proteína; c) otimizamos a geometria do sistema lectina-carboidrato utilizando mecânica molecular clássica; d) criamos o modelo-corte ; e) investigamos as propriedades óticas utilizando HF; f) estudamos as propriedades eletrônicas do sistema proteína-carboidrato e calculamos energias de ligação através do cálculo DFT. O modelo aqui proposto, além de apresentar uma adequada concordância com dados experimentais, abre a possibilidade de investigar propriedades eletrônicas através de uma abordagem quântica estado da arte na área de estrutura eletrônica.

Frutalin is a tetrameric carbohydrate-binding protein obtained from breadfruit seeds. Biomedical interest on Frutalin comes from the high afinity exhibited by these molecules toward carbohydrates expressed by specific tumor cells. So far, no theoretical computational studies have been carried out to investigate the binding characteristics of frutalin, which is probably due to the large number of atoms that should be considered for in silicon calculations. We investigate the binding of frutalin and optical properties with specific carbohydrate molecules using a theoretical cutmodel considering only the carbohydrate binding site. This model has been constructed with the aid of molecular docking and classical molecular mechanics. We use the ab initio all electron reciprocal space Projector Augmented Waves (PAW) method and the Car-Parrinello scheme as embodied in the CP-PAW code to obtain the binding energies. To evaluate the optical properties, we employed the Hartree-Fock Semi-empirical ZINDO method from the Materials Studio 4.0…

Ziel der Masterarbeit ist die Bestimmung der Konformationen und dynamischen Moden von Polymeren unterschiedlicher Topologie in einem Scherung ausgesetzten Fluid. Das simulierte Fluid wird auf charakteristische Eigenschaften getestet. Das Verhalten linearer, ringförmiger und vor allem 3-1-(Trefoil-)verknoteter Polymere in einem Scherung ausgesetzten Fluid wird analysiert. Die Simulation des Fluids erfolgt unter Berücksichtigung der Hydrodynamik, die Integration der Bewegungsgleichungen des Polymers folgt dem für die Molekulardynamik gebräuchlichen Velocity-Verlet-Algorithmus. Zur Berechnung des Fluids wird der Hybridansatz der Multi-Particle Collision Dynamics (MPCD) aufgesetzt, getestet und angewendet. Die Methode bietet eine effiziente und akkurate Kopplung der Polymerdynamik mit der Hydrodynamik des Lösungsmittels. Das Hauptaugenmerk liegt auf dem Zusammenhang zwischen Knotengröße und Winkel zwischen Knotenmittelpunkt und Hauptorientierungsachse relativ zum Polymerschwerpunkt, sowie auf der Bestimmung charakteristischer Formparameter unter Anwesenheit des Knotens im Vergleich mit Ringpolymeren ohne Knoten, jeweils in Abhängigkeit der Weissenbergzahl. Unsere Ergebnisse suggerieren, dass Knoten auf dem 3-1-verknoteten Ring bei hoher Weissenbergzahl eine Tendenz entwickeln, an einem von beiden Enden des Polymers lokalisiert zu sein, parallel zur Flussrichtung. Die mittlere Zahl Beads, welche Teil des Knotens sind, sinkt mit steigender Scherung. Zusätzlich zeigt sich, dass der 3-1-verknotete Ring im Bezug auf Formparameter schneller auf wachsende Scherung reagiert, als gewöhnliche Ringe mit derselben Anzahl von Beads.

The purpose of this Master's Thesis is the calculation of conformations and dynamic modes of polymers of different topologies embedded in a fluid under shear. The simulated fluid is tested for characteristic values. The behavior of linear, circular and, most importantly, 3-1 (trefoil) knotted polymers embedded in the sheared fluid is analysed. The fluid is simulated in agreement with hydrodynamics, the integration of the polymer's equations of motion obeys the Velocity-Verlet algorithm, which is commonly used for molecular dynamics. For reasons of efficiency, the hybrid approach of Multi-Particle Collision Dynamics (MPCD) is set up, tested and employed to compute the fluid. This method provides an efficient and accurate coupling of the polymer's molecular dynamics to the solvent's hydrodynamics. The focus lies on the correlation between knot size and angle between knot center of mass and first principal axis relative to the polymer's center of mass, as well as computation of characteristic shape parameters in presence of a knot in comparison to cyclic polymers without knots, each in dependency of Weissenberg number. We obtain evidence that for the 3-1-knotted ring at high Weissenberg number, knots develop a tendency to be located at either end of the polymer, aligned with the flow. We also find that the average number of beads on the knot decreases with increasing shear.…
