▼ The ability to study ultracold atomic Fermi gases holds the promise of significant advances in testing fundamental theories of many-body quantum physics. Of particular interest are strongly interacting Fermi gases in the BCS to BEC crossover that exhibit a transition to a superfluid state at temperatures near 0.2TF , where TF is the Fermi temperature. This transition, as a fraction of TF, is extremely high compared to any known superfluid or superconductor. These gases are also in a universal regime where the physics is independent of the details of the atomic interactions and is therefore relevant to fields as diverse as condensed matter, nuclear physics and astrophysics. In this thesis, I present an experimental probe of atomic gases that uses momentum-resolved RF spectroscopy to realize an analog of angle-resolved photoemission spectroscopy (ARPES) in materials. This measurement reveals the energy and momentum of single-particle states in the strongly interacting Fermi gas. In condensed matter, ARPES has proved to be one of the most powerful experimental techniques for studying the electronic structure of strongly correlated electron materials. The ability to perform analogous measurements in ultracold Fermi gases constitutes a significant advance in our ability to directly connect ultracold atomic gases to strongly correlated electron systems. Taking advantage of this new measurement technique, I investigate a long-standing problem in the field of strongly interacting fermions, namely whether a pseudogap state consisting of incoherent fermion pairs exists at temperatures above the critical temperature for superfluidity. The photoemission data I present provide strong evidence for this state and have implications for fundamental theories of strongly interacting Fermi gases and strongly correlated electron materials. I also discuss the experimental confirmation of recently predicted universal relations for strongly interacting Fermi gases, as well as some of the first experiments involving atomic Fermi gases with p-wave pairing.

▼ Mesoscopic systems with multi-partite entanglement have applications in quantum computing, quantum communication, quantum cryptography, and quantum enhanced metrology and can give insight into foundational questions of quantum mechanics. Systems in which entanglement develops naturally and persists in the steady state would allow a robust and simple means for creating high-fidelity, multi-partite entangled states. This dissertation lays the foundation for creating highly-entangled Dicke states by such a process in a one-dimensional (1D) gas of fermionic atoms. Toward this end, confinement of fermions in 1D and the rapid introduction of inelastic loss are demonstrated. Rapid interaction control is achieved by driving Raman transitions to transfer atoms between two-component mixtures which exhibit either negligible or rapid inelastic loss. Confinement to 1D is provided by a 2D triangular optical lattice potential. Starting from this incoherent spin-1/2 Fermi gas in 1D, rapid inelastic two-body s-wave collisions should ultimately yield a fully-symmetric Dicke state in the steady state which is useful for multi-party cryptography and quantum enhanced metrology. Strong quantum correlations can also give rise to quantum collective phenomena such as exotic forms of superconductivity and magnetism. Dilute atomic gases are uniquely suited for their systematic investigation since system parameters can be independently tuned. Such studies require the development of new probes. This dissertation also lays the foundation for using quantum noise interferometry to characterize a strongly correlated phase of fermions. This dissertation outlines how to definitively observe the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superfluid phase, an exotic form of superfluidity that coexists with magnetism, by observing quantum noise correlations in the momentum distribution. Rapid transfer between strongly and weakly interacting mixtures, critical for faithfully reproducing the momentum distribution by ballistic expansion, has been demonstrated. The choice of 1D confinement demonstrated here is motivated by the large parameter space anticipated for observing the FFLO phase in 1D. Finally, two new technical developments are presented: the use of molecular iodine transitions as a convenient frequency reference for the primary 6Li resonance and the generation of pure, high-order Laguerre-Gaussian laser beams to enable the study of spatially homogeneous Fermi gases of atoms.

▼ In this thesis we try to understand the unconventional superconducting mechanism on cuprates and organic superconductors (or sodium cobaltates) which can be modeled by a two-dimensional square- and triangular-lattice Hubbard model respectively. The formation of the superconducting dome requires explanations of feasible scenarios. Generally speaking, pairing strength is provided by magnetic fl_x001D_uctuations in the strongly correlated region and the structure of the Fermi surface in this region will favor superconducting pairings with a certain type of symmetry. For the cuprate physics, a superconducting dome composed of d-wave pairings has been identified experimentally. We study the Hubbard model on square lattices and _x001C_find that the pairing strength is originated from anti-ferromagnetic instabilities, and the nearly nested Fermi surface with the square symmetry further supports the d-wave pairing. Moreover, our results show there is a quantum critical point (QCP) beneath the superconducting dome. The QCP is a zero-temperature instability which separates the Fermi liquid and pseudogap regions and exhibits the quantum _x001D_fluctuations which may lead to a high superconducting transition temperature. Above the QCP, a V-shape marginal Fermi liquid region associated with the quantum critical phenomena is also identi_x001C_fied. Using next-nearest-neighbor hopping, chemical potential, and temperature as control parameters, there is a line of Lifshitz transition associated with the change of topology of the Fermi surface. Along the Lifshitz line with t'<=0, the marginal Fermi liquid region prevails, the peak of density of states crosses the Fermi level, and the bare d-wave pairing susceptibility shows a universal scaling with the exponent consistent with theoretical proposals. For the triangular-lattice Hubbard model in the strongly correlated region, we _x001C_find a d+id superconducting pairing on the hole-doped side of the phase diagram. Here the pairing strength comes from the instabilities of the anti-ferromagnetic order (120-degree-spin structure), and the nested hexagon-deformed Fermi surface with the triangular symmetry further boosts the d+id symmetry. Due to the strong competition between electronic interactions and geometric frustrations, the superconductivity and other novel features of the system equal to or above half fi_x001C_lling requires future studies. The numerical tool we apply to study these systems is the dynamical cluster approximation with continuous-time quantum Monte Carlo as the solver. Our approach includes nonlocal correlations embedded in a mean _x001C_field host and is a most up-to-date and reliable approach in dealing with the above mentioned strongly correlated systems valid in the thermodynamic limit. Our _x001C_findings shine light on future investigations of the nature of the unconventional superconductivity in the Hubbard model.

▼ Shale oil production from plays such as the Bakken and Eagle Ford, driven by advances in horizontal well drilling and hydraulic fracturing technology, has helped improve US domestic oil production. However, due to the low permeability of shale oil reservoirs, primary depletion only produces 5 – 10% of the original oil in place and there is an enormous potential for improved recovery. Chemical and gas huff-and-puff methods have been piloted with varying degrees of success, but no breakthrough recovery method has been discovered. In this study, we examined improved oil recovery from shale reservoirs by thermal stimulation, consisting of primary depletion (early in a well’s life), followed by conversion of the well to a heat injector to elevate reservoir temperature, and finally a secondary depletion. A 2D black oil, thermal, reactive transport simulator was developed to test the viability of the proposed method and then CMG STARS, a more advanced compositional/thermal simulator, was used to investigate the mechanisms involved, as well as key parameters affecting recovery during thermal stimulation. We found that 1000 days of thermal stimulation with a 700 °F heater has the potential to increase economical oil recovery from about 7% to more than 11.5%, with potential for even greater recovery if heat injection time and temperature are optimized, as well as if heat is injected while producing oil from an adjacent well. Thermal pressurization of oil is the primary mechanism for the improved recovery. Kerogen decomposition into oil and gas results in a significant increase of hydrocarbons in place but is only a minor contribution to the additional recovery because production is limited by a lack of flow capacity. Furthermore, a two-fold increase in permeability is observed as a result of kerogen decomposition, but its contribution to recovery is also minor because the heated region is not well connected with the fractured region. The heating scheme may be improved in the future to better connect the heated region with the fractured region. Advisors/Committee Members: Balhoff, Matthew T.

▼ This dissertation is composed of two parts. The first part concerns the metalattices, a new type of three-dimensional nanostructured material where we explore the effect of nanoscale geometrical constraint on electron localization in disordered systems. Metalattices are synthesized in late Prof. John Badding’s lab by infiltrating self-assembled SiO2 nanosphere templates using high pressure confined chemical vapor deposition (HPcCVD) technique. Besides a periodicity on 10~100 nm scale, a large surface to volume ratio and geometrical confinement are two major new variables that metalattice structure bring in. Polycrystalline 30 nm platinum metalattices exhibit weakly localized electrical transport. An anomaly in its temperature-dependent low-field magnetoresistance is found, which bears features characteristic of weak localization effect but not shared by Pt thin films or bulk Pt. We attribute the anomaly to the increased electron-phonon scattering due to large surface to volume ratio in Pt metalattices. Our analysis also reveals that the inhomogeneity introduced by metalattice structure cannot be ignored on the length scales relevant for weak localization in 30 nm Pt metalattices. We next investigate heavily doped silicon metalattices of three different periodicities (14 nm, 30 nm, and 100 nm) to explore the effect of geometrical constraint. When the characteristic scale becomes smaller and comparable to the Bohr radius of dopants, one would expect stronger electron localization and an increased critical doping level. We did not observe a metallic phase in 100 nm Si metalattices with a carrier density of 3×10¹⁹ 〖cm〗^(-3), which is above the critical doping level estimated using Shklovskii’s formula for nanocrystal arrays. Our analysis suggests that polycrystallinity in our samples alone cannot explain the absence of metallic phases. We attribute the latter to surface traps on the Si/SiO2 interface, the disorder in the superlattice, and defects or amorphous regions in Si. Future study on high-quality samples is needed to differentiate and quantify effects due to those variables. Our 14 nm and 30 nm samples show Efros-Shklovskii Variable-range hopping type behavior. The model of multiple co-tunneling gives a satisfactory description of the temperature dependence of zero-bias conductance and current-voltage characteristics, consistent with the theory that multiple co-tunneling is the intergranular transport mechanism in a granular electronic system. The second part of this dissertation concerns the magnetoelectrical transport properties of Dirac nodal line semimetal (DNLSM) ZrSiS. Single-crystal ZrSiS is obtained by mechanical exfoliation and provides the opportunity to explore the effects of the electronic band structure. The angle-dependent magnetoresistance under two configurations, together with the traditional Shubnikov de-Hass (SdH) study, provides us with detailed information on the Fermi surface of ZrSiS. We find SdH oscillations with frequencies consistent with results from recent… Advisors/Committee Members: Ying Liu, Dissertation Advisor/Co-Advisor, Ying Liu, Committee Chair/Co-Chair, Nitin Samarth, Committee Member, Chaoxing Liu, Committee Member, Thomas Nelson Jackson, Outside Member, Nitin Samarth, Program Head/Chair.

▼ The recent dominant trends in condensed matter physics research can be roughly summarized into three newly discovered materials: topological insulators, graphene, and iron‐based superconductors. All these materials exhibit many intriguing properties which are fundamentally related to their electronic band structure. Therefore, this lead to many intense investigations on multi‐band electronic system to explore new physics. ❧ The physics of multi‐band electronic structure is fascinating in several aspects. Without many‐body effects, because of the gauge freedom of Bloch states, topological insulators can give rise a robust metallic behavior at its boundaries. In graphene, the touching between conduction and valence band at Fermi level yields a new criticality class which exhibit many unconventional electronic properties, especially its quasi‐relativistic behavior. Turning to the many‐body effects, for instance, the iron‐based superconductors can sustain an superconducting ground state despite of no attractive interactions in the system. Therefore, a deeper understanding for the conventional notions in condensed matter physics has put forward by many of these experimental observations. ❧ In this thesis, the many‐body effects in multi‐band systems are the main focus, especially the study of graphene and iron‐based superconductors which can be compared to experiments. These theoretical studies intend to understand how the underlying electronic bands degree of freedom can give rise to Fermi‐liquid instabilities, and how these effects can be related to intriguing physical properties. ❧ We first study the electrons correlation effects in bilayer graphene by a renormalization group technique. In this study, we build a microscopic model of bilayer graphene from a tight‐binding approach. In our finding, the peculiar Fermi surface configuration leads to critical behavior which is beyond the Fermi‐liquid paradigm. Furthermore, due to the electron‐electron interactions between different bands, excitonic instabilities are found in many different scattering channels. This analysis suggest a collection of competing orders in the system ground states. This result is consistent with the experimental observation that bilayer graphene is an insulator. ❧ Next, we study nematic order in the metallic phase of iron pnictides. In contrast to graphene, the density of states is finite at the Fermi surface. By careful investigating the scattering processes near these Fermi surface, and then identifying the most relevant collective modes from these processes, we find that a Pomeranchuk instability can be driven by magnetic fluctuations. This instability eventually leads to the break down of the isotropic metallic phase which electronic system exhibit broken crystalline rotational symmetry but preserve translation symmetry. As the experiment suggests, this can be a candidate for nematic order in the metallic phase. Advisors/Committee Members: Haas, Stephan W.

▼ This dissertation reports on experimental studies of universal three-body physics in an ultracold Fermi gas. The sample consists of lithium-6 atoms occupying an incoherent mixture of the three lowest energy hyperfine spin states in thermal equilibrium. Using an externally applied magnetic field, three overlapping Feshbach resonances among the various two-body scattering channels were used to tune the s-wave interactions. In the range of magnetic fields from 0 to 1500 Gauss, the three s-wave scattering lengths were widely tunable from the non-interacting limit to deeply within the universal regime where the behavior of the gas is independent of the microscopic details of the inter-particle interactions. We measured the stability of the gas over the ranges of magnetic fields from 0 to 690 Gauss and 834 to 1500 Gauss where all pairwise interactions are attractive and find that the threebody recombination rate constant in these regions varies by over eight orders of magnitude. Further, we observe resonant loss features in the low field region near 130 and 500 Gauss, and a narrow feature in the high field region at 895 Gauss. Recent calculations indicate that these loss features arise from a series of universal three-body bound states (Efimov trimers) near threshold. Our determinations of the three-body parameters in these regimes are used to perform the first complete calculation of the spectrum of Efimov states in any Fermi system. Further, we have realized degeneracy of a three spin-state Fermi gas in the high-field limit where all three inter-particle scattering lengths converge, exhibiting universal quantum physics in the SU(3) symmetric regime. Finally, we preformed a numerical simulation of a novel cooling scheme, demonstrating the feasibility of producing multi-component Fermi gasses with temperatures on the order of 10^(-3) of the Fermi temperature in a combined three-dimensional optical lattice and Laguerre- Gaussian trapping potential. These investigations will guide future experiments aimed at achieving three component (color) superfluidity and exotic magnetic ordering in three-state Fermi gases which have no solid-state analog.

Dans ce travail nous étudions les collisions 40,48 Ca + 40,48 Ca à E = 35 AMeV , mesurées au GANIL avec le couplage unique du spectromètre VAMOS et du multi-détecteur INDRA. Lors de telles collisions les modèles dynamiques prédisent la formation d’un col à basse densité entre deux fragments chauds cinématiquement proches du projectile et de la cible. L’identification isotopique du projectile désexcité (PLF) apportée par VAMOS, et la topologie des espèces détectées en coïncidence dans INDRA, montrent que l’ évolution du rapport N/Z des produits est influencée par le N/Z du système (projectile et cible). Les multiplicités moyennes des particules légères chargées (LCP, Z ≤ 2) suivent en particulier une hiérarchie selon le N/Z du système, et celles des deutons et particules alphas semblent refléter une production dynamique. Une étude des rapports isotopiques a ensuite mis en exergue les mécanismes de transport de l’isospin : la migration et la diffusion de l’isospin, tous deux liés au terme d’ énergie de symétrie de l’ équation d’ état nucléaire. Un objectif de ce travail a été notamment de contraindre les modèles théoriques grâce à l’expérience. Nous avons ainsi appliqué une étude comparative entre les données, le modèle géométrique ELIE et le modèle de transport AMD, désexcités par le code GEMINI++ et filtrés. Cette étude a mis en exergue que le modèle AMD avec un potentiel effectif Gogny asysoft reproduit mieux l’ évolution expérimentale du N/Z du PLF et la hiérarchie des multiplicités des LCP. Enfin nous avons observé que les rapports isotopiques issus des modèles ne reproduisent pas d’enrichissement en neutrons à la mi-rapidité contrairement à l’expérience.

In this work we study the 40,48 Ca+ 40,48 Ca collisions at E = 35 AM eV , measured at GANIL with the coupling of the large acceptance spectrometer VAMOS and the multi-detector array INDRA. During such collisions transport models predict the formation of a low-density neckbetween two hot fragments kinematicaly close to the projectile and the target. The isotopic identification of the projectile-like fragment (PLF) provided by VAMOS, coupled to the topology of the light-charged particles (LCP) detected in coincidence with INDRA, show that the N/Z ratio of the products is influenced by the N/Z of the system (projectile and target). The mean multiplicities associated to the LCP follow a hierarchy according to the system, and the one associated to deuterons and α particles may well reflect a dynamical production. A studyof the isotopic ratios have highlighted isospin transport mechanisms : the isospin drift and the isospin diffusion, both linked to the symmetry energy term of the nuclear equation of state. A goal of this work was also to constrain theoretical models using experiment. We have thenapplied a systematic study to compare data with the geometrical model elie and the transport model amd, both filtered, and using gemini++ as after-burner. This study have highlighted that the amd model with an asysoft equation of state better fits the experimental…

▼ Quantum spin liquids(QSL) have fascinated physicists for nearly half a century since Anderson first introduced this concept with his resonating-valence-bond(RVB) idea in 1973. Although many progresses had been made, more challenges emerge from both theoretical and experimental perspectives. On the theory side, dealing with quantum mechanics acting on the spin system forces theorists to leave the comfort zone of semi-classical approaches. On the experimental side, high-quality QSL candidates remain very scarce, and the experimental results are often contradictory and inconclusive. In this thesis, I will present and discuss our thermal transport results on three different candidate materials with novel thermal conductivity and thermal Hall features that serve as crucial hallmarks for identifying and classifying the QSL materials. We introduce the theoretical frameworks for the antiferromagnetic(AFM) spin-1/2 Heisenberg system and Kitaev model. Transport theories of spin system, which are closely relevant to our results, are briefly discussed. After introducing the theoretical and experimental background, we report our discoveries on Na2BaCo(PO4)2, an AFM spin-1/2 system with geometry frustration of the triangular lattice. As thermal conductivity and Hall coefficients measured down to 0.3 K, we reveal a new gapless QSL state that exhibits unusual Hall effect in this charge-neutral system. Combining inelastic neutron scattering(INS) study, we confirm the observed QSL state hosts energy-continuous spin excitation, which is highly related to the theoretical prediction of spinon. The third and fourth chapters of this thesis are dedicated to BaCo2(AsO4)2 and α-RuCl3, which are promising candidates for realizing the Kitaev model. We report thermal conductivity and Hall coefficients of both materials measured down to 0.3K. The observed thermal conductivity oscillations with novel angle dependence in α-RuCl3 strongly suggest a quantum oscillation mechanism that arises from the charge-neutral Fermi surface. Oscillatory behavior of thermal conductivity in BaCo2(AsO4)2 appears to be ’chaotic’ and remain unexplored theoretically. With the magnetic hysteresis carefully subtracted, we obtain the intrinsic thermal Hall effects of both materials and compare our results with other related works. We discuss the insights and limitations of our experiments, as well as future work. Advisors/Committee Members: Ong, Nai Phuan (advisor).
