▼ This thesis applies the recently developed dynamic van der Waals theory to perform two-dimensional numerical simulations for two-phase, one-component, non-isothermal, liquid-vapour systems. This model has recently been utilised to produce physically reasonable semi-quantitative results in systems where complicated dynamics restrict alternative methods. Two types of boiling are studied; where problematic features, such as non-uniform temperature and phase transition, are principal characteristics: (i) The effects of substrate wettability in pool boiling: (ii) The applicability of the lubrication approximation to Leidenfrost drops, and the similarities between coalescing non-wetting drops and Leidenfrost drops. Experimental study of these problems is challenging due to the small length scales involved, while numerical simulations can resolve the necessary detail. In pool boiling, bubble growth rate on non-wetting surfaces is seen to be larger than that on wetting surfaces. This is explained by noting that the factors contributing to the rate of bubble growth include not only the strong evaporation at the thermal singularity but also the evaporation from a portion of interface close to the substrate. Based on this, an expression is derived for the contact line speed, showing good agreement with the simulation results. The solutions derived from the lubrication approximation for Leidenfrost drops are found to generally compare well to the simulation results. The robustness of the lubrication approximation is attributed to the common features found in the pressure variation through \he vapour layer, although it breaks down as the evaporative region near the interface is approached. Numerical studies of Leidenfrost drop coalescence find a build-up of vapour in the common space under both drops causing a short-range repulsion. This is achieved through a pressure change that scales in a similar manner to that under a single drop. A threshold drop size exists in order for a horizontal body force to overcome the repulsion.

▼ Correlation methods within electronic structure theory focus on recovering the exact electron-electron interaction from the mean-field reference. For most chemical systems, including dynamic correlation, the correlation of the movement of electrons proves to be sufficient, yet exact methods for capturing dynamic correlation inherently scale polynomially with system size despite the locality of the electron cusp. This work explores a new family of methods for enhancing the locality of dynamic correlation methodologies with an aim toward improving accuracy and scalability. The introduction of range-separation into ab initio wavefunction methods produces short-range correlation methodologies, which can be supplemented with much faster approximate methods for long-range interactions.First, I examine attenuation of second-order Møller-Plesset perturbation theory (MP2) in the aug-cc-pVDZ basis. MP2 treats electron correlation at low computational cost, but suffers from basis set superposition error (BSSE) and fundamental inaccuracies in long-range contributions. The cost differential between complete basis set (CBS) and small basis MP2 restricts system sizes where BSSE can be removed. Range-separation of MP2 could yield more tractable and/or accurate forms for short- and long-range correlation. Retaining only short-range contributions proves to be effective for MP2 in the small aug-cc-pVDZ (aDZ) basis. Using one range-separation parameter within either the complementary error function (erfc) or a sum of two error functions (terfc), superior behavior is obtained versus both MP2/aDZ and MP2/CBS for inter- and intra-molecular test sets. Attenuation of the long-range helps to cancel both BSSE and intrinsic MP2 errors. Direct scaling of the MP2 correlation energy (SMP2) proves useful as well. The resulting SMP2/aDZ, MP2(erfc, aDZ), and MP2(terfc, aDZ) methods perform far better than MP2/aDZ across systems with hydrogen-bonding, dispersion, and mixed interactions at a fraction of MP2/CBS computational cost.Second, attenuated MP2 is developed within the larger aug-cc-pVTZ (aTZ) basis set for inter- and intramolecular non-bonded interactions. A single attenuation parameter is optimized on the S66 database of 66 intermolecular interactions, leading to a very large RMS error reduction by a factor of greater than 5 relative to standard MP2/aTZ. Attenuation introduces an error of opposite sign to basis set superposition error (BSSE) and overestimation of dispersion interactions in finite basis MP2. A variety of tests including the S22 set, conformer energies of peptides, alkanes, sugars, sulfate-water clusters, and the coronene dimer establish the transferability of the MP2(terfc, aTZ) model to other inter and intra-molecular interactions. Direct comparisons against attenuation in the smaller aug-cc-pVDZ basis shows that MP2(terfc, aTZ) often significantly outperforms MP2(terfc, aDZ), although at higher computational cost. MP2(terfc, aDZ) and MP2(terfc, aTZ) often outperform MP2 at the complete basis set limit.…

▼

The van der Waals forces, which are forces between neutral atoms and molecules, play an important role in physics (e.g. in phase transitions), chemistry (e.g. in chemical reactions) and biology (e.g. in determining properties of DNA). These forces are of quantum nature and it is long being conjectured and experimentally verified that they have universal behaviour at large separations: they are attractive and decay as the inverse sixth power of the pairwise distance between the atoms or molecules. In this thesis we prove the van der Waals law under the technical condition that ionization energies (energies of removing electrons) of atoms are larger than electron affinities (energies released when adding electrons). This condition is well justified experimentally as can be seen from the table, \newline \begin{tabular}{|c|c|c|c|} \hline Atomic number & Element & Ionization energy (kcal/mol)& Electron affinity (kcal/mol) \\ \hline 1 & H & 313.5 & 17.3 \\ \hline 6 & C & 259.6 & 29 \\ \hline 8 & O & 314.0 & 34 \\ \hline 9 & F & 401.8 & 79.5 \\ \hline 16 & S & 238.9 & 47 \\ \hline 17 & Cl & 300.0 & 83.4 \\ \hline \end{tabular} \newline where we give ionization energies and electron affinities for a small sample of atoms, and is obvious from heuristic considerations (the attraction of an electron to a positive ion is much stronger than to a neutral atom), however it is not proved so far rigorously. We verify this condition for systems of hydrogen atoms. With an informal definition of the cohesive energy W(y), y=(y₁,...,y_M) between M atoms as the difference between the lowest (ground state) energy, E(y), of the system of the atoms with their nuclei fixed at the positions y₁,...,y_M and the sum, ∑_j=1^M E_j, of lowest (ground state) energies of the non-interacting atoms, we show that for |y_i-y_j|, i,j ∈ {1,...,M}, i \neq j, large enough, W(y)=-∑_i<j^1,M \frac{σ_ij}{|y_i-y_j|⁶}+O(∑_i<j^1,M \frac{1}{|y_i-y_j|⁷}) where σ_ij are in principle computable positive constants depending on the nature of the atoms i and j.

▼ This dissertation focused on the potential use of highly charged nanoparticles to stabilize dispersions of weakly charged microparticles. The experimental components of the project centered on a model colloidal system containing silica microparticles at the isoelectric point where the suspensions are unstable and prone to flocculation. The stability of the silica suspensions was studied in the presence of highly charged nanoparticles. Initial experiments used polystyrene latex with either sulfate or amidine surface groups. Effective zeta potentials were measured with nanoparticle concentrations ranging from 0.001% to 0.5% vol. Adsorption levels were determined through direct SEM imaging of the silica microparticles, showing that the nanoparticles directly adsorbed to the microparticles (amidine more than sulfate), producing relatively large effective zeta potentials. However, stability experiments showed that the latex nanoparticles did not stabilize the silica but merely provided a reduction in overall flocculation rate. It was concluded that the zeta potential was an insufficient predictor of stability as there was still sufficient patchiness on the surface to allow for the silica surfaces to aggregate. Experiments using zirconia and alumina nanoparticles did achieve effective stabilization; both types stabilized the silica suspensions for longer than the observation period of approximately 15 hours. Stability was observed at concentrations of 10^-4% to 1.0% (zirconia) and 10^-2% vol. (alumina). These particles adsorbed directly to the microparticles (confirmed via SEM) and produced increasing effective zeta potentials with increasing nanoparticle concentrations. The adsorption resulted in significant electrostatic repulsion that was determined to be effectively irreversible using colloidal probe AFM. The improved stabilizing ability was attributed to the increased van der Waals attraction between the oxide nanoparticles (compared to polystyrene). Finally, an unexpected result of the CP-AFM force measurements showed that the repulsive forces between a nanoparticle-coated particle and plate lacked the normal dependence on the radius of the probe as predicted by the Derjaguin approximation. The forces observed in nanoparticle suspensions were virtually identical for 5 µm and 30 µm probes. Based on calculations of the shear rate in the gap, it was theorized that this phenomenon may have resulted from the shearing of adsorbed particles from the surfaces, which leads to similar interaction geometries for the two probe sizes.

▼ Van der Waals molecules are complexes of two or more atoms or molecules bound by weak intermolecular forces rather than a conventional chemical bond. This thesis contains a high resolution molecular beam study of the rotational spectra of two such species, ArNO and NeNO. A new hamiltonian is presented to account for the spectra of these open-shell complexes. The theory is similar to that already known for the uncomplexed diatom, nitric oxide, but is modified to an asymmetric top form appropriate for these non-linear species. Two novel interactions require inclusion. The first models a slight quenching of the NO orbital angular momentum by the rare gas atoms. The second is a large centrifugal distortion associated with the effects of the bending motion on the projection of the electronic angular momentum on the complex's a-inertial axis. A comparatively rich, though incomplete, spectrum is obtained for ArNO. Most of the transitions that originate from the lower rotational states are assigned and fitted to within a few MHz using the modified open-shell hamiltonian. Possible sources are suggested for the origins of the small residual errors between the observed and calculated transition frequencies. A vibrationally-averaged structure is derived from the fitted molecular parameters indicating an equilibrium geometry which is quite close to a T-shape. The hyperfine structure in the spectrum which is associated with the ¹⁴ N nucleus is well fitted by the hamiltonian; however, the magnetic hyperfine parameters are significantly perturbed from the values that best fit the lambda-doubling spectrum of the uncomplexed diatom. The implications of this with respect to the nature of the rare gas-nitric oxide intermolecular interaction are discussed. Greater experimental difficulties are encountered in trying to record the radiofrequency and microwave spectrum of NeNO and so fewer transitions have been measured than for ArNO. A partial analysis yields approximate values for the structural parameters. The complex exhibits a larger deviation from the T-shaped geometry than is observed for ArNO. The spectrum also provides an estimate of the magnitude of the quenching of the orbital angular momentum. The quenching interaction is somewhat larger in the neon complex.

La plupart des fonctions énergie potentielle utilisées pour simuler les systèmes biologiques complexes ne traitent qu'implicitement la polarisation électronique et ce, de façon très incomplète. Bien qu'efficaces pour un large éventail d'applications, ces champs de force atteignent rapidement leurs limites dès lors que les effets de polarisation électronique sont importants. Tel est le cas par exemple au site actif des métalloprotéines où l'ion métallique polarise fortement son environnement. Dans cette thèse, j'ai développé une approche basée sur la mécanique quantique pour obtenir des paramètres d'un champ de force polarisable ayant pour composantes des charges, des polarisabilités distribuées d'ordre zéro et un (isotrope) et un potentiel de van der Waals décrit par une fonction de Buckingham. L'énergie d'induction peut être atténuée par une fonction de Tang et Toennies pour décrire l'énergie d'échange-induction. Cette approche a été effectuée avec succès pour l'interaction d'ions avec l'eau et le benzène mais aussi dans le cas d'un dimère d'eau. Une première étude des résultats en dynamique moléculaire montre que les paramètres obtenus en phase gazeuse peuvent se transférer pour les simulations en phase condensée

Most of the energy potential functional used in biological systems only treat electronic polarization implicitely and this, in an incomplete way. Even very effective for many applications, those force fields reach there limits when the polarization effects are important. This is the case, for example, at the active site of metalloproteins where the metallic ion heavily polarizes its environment. We will present a strategy to take into account the polarization through polarizability distributed on atoms obtained by quantum chemical calculations. The interaction energies have been compared with a reference SAPT (it{Symmetry Adapted Perturbation Theory}) calculation which permits to expand the interaction in electrostatics, induction and van der Waals contributions. I will present the interaction of ions with water, benzene and also water dimer interactions. Preliminary results in molecular dynamics seems to confirm that gas phase parameters can be transfered to condensed phase

▼ The investigation of van der Waals forces is very important to understand nature in a complete way seeing that many appealing processes and properties of materials are determined by these noncovalent interactions such as atom/molecules adsorptions and binding energies of low dimensional materials. Computational methods based on density functional theory (DFT) have made great advancement on describing these long-ranged interactions and helped researchers to better understand the mechanisms behind these phenomena. In this thesis, we theoretically examined the significance of vdW interactions in the applications of energy materials, including batteries, thermoelectrics, and catalysts for ammonia synthesis. The intercalation behaviours of metal atoms on MoS2/graphene heterostructure were studied, which helped to elucidate the origins behind the enhanced properties in hybrid structures compared to monolayer MoS2 or graphene. Many body interaction energies were calculated as the indicator of ``synergistic effects'', which showed that cooperative bindings were obtained only when Mg and Ca were intercalated between MoS2 and graphene. In other situations, the metals showed either additive or anti-cooperative behaviours, which demonstrated that the enhanced properties were mainly owing to the increasing surface areas in the bilayer heterostructures.Secondly, we assess the performance of (dispersion-correlated) DFT methods in describing the lattice dynamics of layered materials, using TiS2 as a prototypical system. Fractional ionic approach (FIA) was selected as the benchmark because of its accurate predictions of layered materials. VdW-inclusive Tkatchenko-Scheffler (TS) and Grimme's DFT-D3 methods demonstrated consistent compared to the benchmarking values while traditional Perdew-Burke-Ernzerhof (PBE) functional and PBE+U (PBE functional with the revision of the on-site Coulomb interaction of localized electrons) had considerable deviation due to lack of descriptions of nonlocal dispersion interactions in the functionals.Finally candidate solid-state catalysis for solar thermal ammonia synthesis was assessed with dispersion-corrected DFT. We calculated the forward reaction enthalpies for the processes of reduction, nitration, and hydrolysis. CoMoO4/Co3Mo3N, NiMoO4/Ni3Mo3N, and ZnMoO4/ZnMoN2 were selected as candidate catalytic pairs where ZnMoO4 had the lowest reaction energy barrier reduced by carbonaceous agent while CoMoO4/Co3Mo3N and NiMoO4/Ni3Mo3N were more likely to yield larger amount of NH3 owing to the energetic propensity in last two steps.Outcomes of these works form the basis for our future works in high-throughput screenings of functional materials for energy-storage and solid-state solar-thermal catalytic applications.

La plupart des objets quantiques individuels développés jusqu’à aujourd’hui ne permettent pas de satisfaire toutes les conditions nécessaires pour la construction d’un simulateur quantique. Une possibilité pour obtenir un système quantique robuste est de combiner plusieurs de ces approches. Dans cette thèse, nous décrivons les résultats obtenus sur deux systèmes expérimentaux développés dans ce but.La première partie de cette thèse décrit un système hybride d’atomes neutres couplés à des qubits supraconducteurs, en construction à l’Université du Maryland. La solution envisagée pour placer un ensemble d’atomes froids à proximité de la surface supraconductrice est de piéger les atomes dans le champ évanescent se propageant autour d’une fibre optique nanométrique. Nous avons développé un dispositif permettant la production de fibres optiques nanométriques de transmission optique supérieure à 99.95% dans le mode fondamental. Nous avons également optimisé la transmission de quelques modes d’ordres supérieurs, ce qui pourra s’avérer utile pour le piégeage d’atomes.La seconde partie de cette thèse décrit un système développé à l’Institut d’Optique et comprenant des atomes neutres piégés dans des matrices de pinces optiques. Dans ce cas, nous excitons les atomes dans des états de Rydberg afin de bénéficier de fortes interactions interatomiques. Nous avons caractérisé les interactions de van der Waals et les interactions résonantes entre deux atomes individuels, et démontré le caractère cohérent de l’interaction dipolaire. Nous avons enfin simulé la dynamique d’une chaine élémentaire de spins dans une matrice de trois atomes

Most platforms that are being developed to build quantum simulators do not satisfy simultaneously all the requirements necessary to implement useful quantum tasks. Robust systems can be constructed by combining the strengths of multiple approaches while hopefully compensating for their weaknesses. This thesis reports on the progress made on two different setups that are being developed toward this goal.The first part of this thesis focuses on a hybrid system of neutral atoms coupled to superconducting qubits that is under construction at the University of Maryland. Sub-wavelength diameter optical fibers allow confining an ensemble of cold atoms in the evanescent field surrounding the fiber, which makes them ideal for placing atoms near a superconducting surface. We have developed a tapered fiber fabrication apparatus, and measured an optical transmission in excess of 99.95% for the fundamental mode. We have also optimized tapered fibers that can support higher-order optical modes with high transmission, which may be useful for various optical potential geometries.The second part of this thesis focuses on a system of neutral atoms trapped in arrays of optical tweezers that has been developed at the Institut d’Optique. Placing the atoms in highly excited Rydberg states allows us to obtain strong interatomic interactions. Using two individual atoms, we have characterized the pairwise interactions in the…

Depuis son invention en 1986, les microscopes à force atomique (AFM) ont été des puissants outils pour la caractérisation des matériaux et des propriétés des matériaux à l'échelle nanométrique. Cette thèse est entièrement dédiée à la mesure de l'interaction entre une sonde AFM et une surface avec une nouvelle technique AFM appelée Force Feedback Microscopy (FFM). La technique a été développée et utilisée pour l'étude d'échantillons biologiques. Le principe central de la technologie FFM est que la force totale moyenne appliquée à la pointe est égal à zéro. En conséquence, en présence d'une interaction pointe-échantillon, une force égale et contraire doit être appliqué à la pointe par une boucle de rétroaction . La force de réaction est ici appliquée à la pointe à travers le déplacement d'un petit élément piézoélectrique positionné à la base du levier AFM. La boucle de rétroaction permet d'éviter instabilités mécaniques tels que le saut au contact, permettant la mesure complète de la courbe d'interaction. En plus, il donne la possibilité de mesurer simultanément les parties élastique et inélastique de l'interaction.La technique a été appliquée à l'étude des interactions à l'interface solide/gaz, avec un intérêt particulier pour l'observation de la formation et de la rupture des ponts capillaires entre pointe et échantillon. Ensuite, on a focalisé notre attention aux interfaces solide/liquide. Dans ce contexte, courbes complètes de type DLVO sont caractérisées d'un point de vue élastique et dissipatif.Nous avons développé des nouveaux modes d'imagerie AFM pour l'étude des biomolécules. Images de phospholipides et de l'ADN à force constante ont été réalisées et certaines propriétés mécaniques comme le module de Young des échantillons ont été évaluées. En plus, nous avons réalisé une étude spectroscopique de l'élasticité et du coefficient d'amortissement de l'interaction entre des cellules vivantes de type PC-12 et une pointe AFM en silicium. L'étude montre que le FFM est un instrument capable de mesurer l'interaction à des fréquences qui ne sont pas nécessairement liées aux résonances caractéristiques du levier. L'étude spectroscopique pourrait avoir dans le futur des applications importantes pour l'étude des bio-molécules et des polymères.

Since its invention in 1986, the atomic force microscopes (AFMs) have been powerful tools for the characterization of materials and material properties at the nanoscale. The present thesis focuses on the measurement of the interaction between an AFM probe and a surface. A new AFM technique called Force Feedback Microscopy (FFM) has been developed and applied to the study of biological specimens. The central principle of the FFM is that the average total force acting on the tip is maintained equal to zero. It means that, in presence of a tip-sample interaction, a counteracting force has to be applied to the tip by a feedback loop. We apply a counteracting force to the tip by displacing the cantilever base with a small piezoelectric element. The feedback loop avoids mechanical…

On considère un système constitué de plusieurs atomes où les noyaux sont supposés fixes et ponctuels. Les particules interagissent via le potentiel de Coulomb et les électrons ont une énergie cinétique pseudo-relativiste donnée par (p2+m2)1/2-m. On démontre la loi de van der Waals-London qui dit que l'énergie d'interaction entre atomes neutres décroit comme |D|-6 où |D| est la distance entre atomes. Nous calculons rigoureusement tous les termes de l'énergie de liaison jusqu'à l'ordre |D|-9 avec un terme d'erreur en O(|D|-10). Comme étape intermédiaire, nous établissons la décroissance exponentielle des fonctions propres de l'opérateur de Schrödinger à plusieurs particules avec les symétries imposées par le principe de Pauli, et des estimations sur le terme d'erreur de localisation. Nous montrons de plus la loi de van der Waals-London pour l'opérateur de Dirac projeté connu sous le nom d'opérateur de Brown et Ravenhall. Dans ce dernier cas on obtient un terme d'erreur en O(|D|-7).

We consider a multiatomic system where the nuclei are assumed to be point charges at fixed positions.Particles interact via Coulomb potential and electrons have relativistic kinetic energy given by (p2+m2)1/2-m.We prove the van der Waals-London law, which states that the interaction energy between neutral atoms decays as the sixth power of the distance |D| between the atoms. We rigorously compute all terms in the binding energy up to order |D|-9 with error term of order O(|D|-10). As intermediate steps we prove exponential decay of eigenfunctions of multiparticle Schrödinger operators with permutation symmetry imposed by the Pauli principle and new estimates of the localization error. In addition we prove the van der Waals-London law for the projected Dirac operator, known as the Brown-Ravenhall operator. In this case we do not calculate the coefficients explicitly and we obtain an error term of order O(|D|-7).
