Abstract:

If no Higgs boson exists, scattering amplitudes of massive vector bosons become strong at TeV energies. Below the threshold where new resonances appear, they are described by an effective chiral Lagrangian, which introduces a small number of new universal parameters at each order of a low-energy expansion. These parameters can be measured in (quasi-)elastic scattering processes of massive vector bosons in e-e± collisions. Analyzing processes such as e-e-→νeνeW-W-, a sensitivity of the order 10-2 can be reached at a high-luminosity 1 TeV linear collider.

Abstract:

Possible deviations from a low-energy theorem for the scattering of strongly interacting longitudinally polarized W and Z bosons are discussed within a particular scheme of electroweak symmetry breaking. The scheme (suggested earlier by other authors in a slightly different context) is based on spontaneous breakdown of an SU(4) symmetry to custodial SU(2) subgroup. The physical spectrum of such a model contains a set of relatively light pseudo-Goldstone bosons whose interactions with vector bosons modify the low-energy theorem proven for a "minimal" symmetry-breaking sector The Goldstone-boson manifold SU(4)/SU(2) is not a symmetric space. In this context it is observed that, on the other hand, there is a large class of models of electroweak symmetry breaking, involving groups G and H such that the G/H is a symmetric space and the corresponding rich multiplets of pseudo-Goldstone bosons do not influence the canonical low-energy theorem. For the scheme considered here, the relevant interactions are described in terms of an effective chiral Lagrangian and tree-level contributions of the pseudo-Goldstone boson exchanges to the vector boson scattering are computed explicitly. A comparison with the standard model is made.

Abstract:

The spinor strong interaction model recently proposed to account for the meson spectra is extended to include interaction with external gauge fields. An action integral is constructed and a restricted variational principle is employed to reproduce the earlier basic meson equations. In establishing U(1) gauge invariance, the so-called U(1) problem, the absence of pseudoscalar singlet mesons that do not decay strongly, is naturally resolved. SU(2)× U(1) or SO(3) gauge invariance leads to that pseudoscalar isodoublet or isotriplet mesons can generate masses of the gauge bosons without recourse to the unobserved Higgs bosons of the standard electroweak model. The gauge boson masses relate to the linear confinement potential constant of pseudoscalar mesons. The spinor strong interaction model is quantized in a macroscopic approximation due to the finite size of mesons. Commutation relations and the rest frame Hamiltonian are obtained. In this frame, the relative energy of the quark and antiquark is shown to vanish.

Abstract:

The dynamical origin of electroweak symmetry breaking is an open question with many possible theoretical explanations. Strongly coupled systems predicting the Higgs boson as a bound state of a new gauge-fermion interaction form one class of candidate models. Due to increased statistics, LHC run II will further constrain the phenomenologically viable models in the near future. In the meanwhile it is important to understand the general properties and specific features of the different competing models. In this work we discuss many-flavor gauge-fermion systems that contain both massless (light) and massive fermions. The former provide Goldstone bosons and trigger electroweak symmetry breaking, while the latter indirectly influence the infrared dynamics. Numerical results reveal that such systems can exhibit a light [Formula: see text] isosinglet scalar, well separated from the rest of the spectrum. Further, when we set the scale via the vev of electroweak symmetry breaking, we predict a 2 TeV vector resonance which could be a generic feature of SU(3) gauge theories.

Abstract:

Abstract Fragmentation of bosons and pairs in a trapped imbalanced bosonic mixture is investigated analytically using an exactly solvable model, the generic harmonic-interaction model for mixtures. Closed-form expressions for the eigenvalues and eigenfunctions of the reduced one-particle and two-particle density matrices as a function of all parameters, the masses, numbers of bosons, and the intraspecies and interspecies interactions, are obtained and analyzed. As an application, we consider a system made of N 1 = 100 non-interacting species 1 bosons embedded in a bath made of N 2 = 106 non-interacting species 2 bosons, and show how fragmentation of the system’s bosons and pairs emerges from the system–bath interaction only. Interestingly, the lighter the bosons comprising the bath are the stronger is the system’s fragmentation. Further applications are briefly discussed.

Abstract:

We consider the many-body localization–delocalization transition for strongly interacting one-dimensional disordered bosons and construct the full picture of finite temperature behavior of this system. This picture shows two insulator–fluid transitions at any finite temperature when varying the interaction strength. At weak interactions, an increase in the interaction strength leads to insulator → fluid transition, and, for large interactions, there is a reentrance to the insulator regime. It is feasible to experimentally verify these predictions by tuning the interaction strength with the use of Feshbach or confinement-induced resonances, for example, in 7Li or 39K.

Abstract:

The neutralino sector is analyzed for a supersymmetric nonlinear sigma model. This model describes the low energy physics of strongly interacting theories in which super-symmetry is softly broken at scales below the electroweak symmetry breaking scale. The measured width of the Z boson constrains the allowed range of parameters. In case the lightest neutralino is stable, limits on additional contributions to the invisible width of the Z boson and on the relic neutralino density further restrict parameter space. As a consequence, the lightest neutralino in the considered class of theories is required to have a mass above 15 GeV, but below MZ.

Abstract:

Ultracold atoms in optical lattices offer an important tool for studying dynamics in many-body interacting systems in a pristine environment. This thesis focuses on three theoretical works motivated by recent optical lattice experiments. In the first, we theoretically study the center of mass dynamics of states derived from the disordered Bose-Hubbard model in a trapping potential. We find that the edge states in the trap allow center of mass motion even with insulating states in the center. We identify short and long-time mechanisms for edge state transport in insulating phases. We also argue that the center of mass velocity can aid in identifying a Bose-glass phase. Our zero temperature results offer important insights into mechanisms of transport of atoms in trapped optical lattices while putting bounds on center of mass dynamics expected at non-zero temperature. In the second work, we study the domain wall expansion dynamics of strongly interacting bosons in 2D optical lattices with disorder in a recent experiment {[}J.-y. Choi et al., Science 352, 1547 (2016)]. We show that Gutzwiller mean-field theory (GMFT) captures the main experimental observations, which are a result of the competition between disorder and interactions. Our findings highlight the difficulty in distinguishing glassy dynamics, which can be captured by GMFT, and many-body localization, which cannot be captured by GMFT, and indicate the need for further experimental studies of this system. The last work features our study of phase diagrams of the 2D Bose-Hubbard model in an optical lattice with synthetic spin-orbit coupling. We investigate the transitions between superfluids with different phase patterns, which may be detected by measuring the spin-dependent momentum distribution.<br>Ph. D.<br>Ultracold atoms in optical lattices, a periodic potential generated by laser beams, offer an important tool for quantum simulations in a pristine environment. Motivated by recent optical lattice experiments with the implementation of disorder and synthetic spin-orbit coupling, we utilize Gutzwiller mean-field theory (GMFT) to study the dynamics of disordered state in an optical lattice under the sudden shift of the harmonic trap, the domain wall expansion of strongly interacting bosons in 2D lattices with disorder, and spin-orbit-driven transitions in the Bose-Hubbard model. We argue that the center of mass velocity can aid in identifying a Bose-glass phase. Our findings show that evidence for many-body localization claimed in experiments [J.-y. Choi et al., Science 352, 1547 (2016)] must lie in the differences between GMFT and experiments. We also find that strong spin-orbit coupling alone can generate superfluids with finite momentum and staggered phase patterns.

Abstract:

Les atomes froids dans les réseaux optiques permettent d'avoir un contrôle sans précédent des états a N-corps fortement corrélés. Pour cette raison, ils représentent un excellent outil pour l'implémentation d'un « simulateur quantique », utile pour réaliser de manière expérimentale de nombreux hamiltoniens de systèmes d'intérêt physique. En particulier, ils rendent possible la création de champs de jauge artificiels; ces derniers permettant d'accéder à la physique du magnétisme frustré. Dans ce travail, il s'agit de s'intéresser à la thermodynamique des atomes froids, en abordant ce sujet de manière théorique et numérique. A ce jour, le Monte Carlo quantique est la méthode la plus efficace dans ce domaine. Néanmoins, en raison de ce qu'on appelle le « problème du signe », elle ne peut s'appliquer qu'à une classe restreinte de systèmes, et dont par exemple les systèmes frustrés ne font pas partie. L'intérêt de cette thèse est de développer une nouvelle méthode approximée fondée sur une approche Monte Carlo. La première partie de cette thèse est consacrée à des considérations de nature théorique sur la structure spatiale des corrélations classiques et quantiques. Ces résultats nous permettent de développer, dans une deuxième partie, une approximation nommée « champ moyen quantique ». Celle-ci permet de proposer, dans une troisième partie, une méthode numérique qu'on appelle « Monte Carlo du champ auxiliaire » et qu'on applique à des cas d'intérêt physique, notamment au réseau triangulaire frustré<br>Cold atoms in optical lattices offer unprecedented control over strongly correlatedmany-body states. For this reason they represent an excellent tool for the implementation ofa “quantum simulator”, which can be used to realize experimentally several Hamiltonians ofsystems of physical interest. In particular, they enable the engineering of artificial gaugefields, which gives access to the physics of frustrated magnetism. In this work, we study thethermodynamics of cold atoms both from a theoretical and a numerical point of view. Atpresent days, the most effective method used in this field is the quantum Monte Carlo. Butbecause of the so-called “sign problem” it can only be applied to a limited class of systems,which for example do not include frustrated systems. The interest of this thesis is to developof a new approximated method based on a Monte Carlo approach. The first part of this workis dedicated to theoretical considerations concerning the spatial structure of quantum andclassical correlations. These results permit to develop, in the second part, an approximationcalled quantum mean-field. This latter allows to propose, in the third part, a numericalmethod that we call “auxiliary-field Monte Carlo” and that we apply to some systems ofphysical interest, among which the frustrated triangular lattice

Abstract:

Les systèmes de spin antiferromagnétiques en une dimension présentent des caractéristiques remarquables. Le théorème de Mermin-Wagner montre que même dans l'état fondamental de leur Hamiltonien, ces systèmes ne possèdent pas d'ordre à longue distance dans leurs fonctions de corrélation spin-spin s'ils possèdent une symétrie continue. Néanmoins, un quasi-ordre à longue distance peut exister, avec des fonctions de corrélation spin-spin décroissant en loi de puissance avec la distance, comme par exemple dans la chaîne de spin-1/2. Ce cas est décrit par la théorie des liquides de Luttinger. Même dans le cas d'un ordre à courte distance où les fonctions de corrélations spin-spin décroissent exponentiellement, un ordre topologique peut être présent. Il peut être mis en évidence par un paramètre d'ordre dépendant des opérateurs de spin de façon non-locale ou par la présence d'excitations de bord, comme par exemple dans le cas de la chaînes de spin-1. D'autre part, il existe une équivalence formelle entre les opérateurs de spin-1/2 et les bosons de coeur dur, qui permet de traduire les propriétés des systèmes magnétiques dans le langage des bosons en interaction. Après une rapide revue des méthodes théoriques utilisées pour la description des systèmes de basse dimensionnalité, je décrirais mes travaux sur les systèmes échelles de spin antiferromagnétiques et les applications aux systèmes de bosons en interaction.

Abstract:

Les systèmes fortement corrélés, pouvant adopter des phases surprenantes de la matière, émergent dans le domaine des atomes ultra-froids ou dans celui de l’électrodynamique quantique en cavité (CQED). Ceux-ci sont au centre d’intenses travaux expérimentaux et théoriques. Dans cette thèse, nous présentons une étude de deux modèles de bosons avec deux ou zéro états internes. Ceux-ci peuvent se déplacer sur un réseau, et sont localement couplés avec des spins 1/2. Notre intérêt réside dans la détermination du diagramme de phase de l’état fondamental de ces systèmes ainsi que de l’étude des propriétés de phase et des transitions entre ces dernières. Nous avons utilisé deux outils : une approximation de champ moyen et des simulations de Monte-Carlo quantique, qui fournit des résultats numériquement exacts. Le premier modèle, appelé modèle de Kondo bosonique sur réseau, s’inscrit dans le contexte des atomes ultra-froids sur réseau. Nous trouvons que sa physique est proche de celle du modèle de Bose-Hubbard, présentant des phases de Mott et superfluide. Le couplage local renforce le caractère isolant et on observe l’émergence de phases magnétiques au travers de couplage direct ou indirect entre bosons et/ou spins. Les effets thermiques, inhérents à tout dispositif expériemental, sont aussi étudiés. Le second modèle s’inscrit dans le domaine de la CQED sur réseau, décrit un régime de couplage ultra-fort entre des photons et des atomes, et est appelé modèle de Rabi sur réseau. Le diagramme de phase présente juste deux phases : une phase cohérente dans laquelle les spins locaux s’ordonnent ferromagnétiquement ainsi qu’une phase incohérente compressible paramagnétique<br>Strongly correlated systems, where new surprising phases of matter may appear both in the context of ultra-cold atoms and cavity quantum electrodynamics, are the focus of intense experimental and theoritical activity. In this thesis we present a study of two models of bosons with two or zero internal states, that is to say spin-1/2 or spin-0 bosons. These particles can move around a lattice, and they are locally coupled to immobile spins 1/2. Our interest was to determine the ground state phase diagram, study phase properties and quantum phase transitions. We used two methods: an approximate one using a mean field approach and the other using quantum Monte-Carlo simulations, which provides numerically exact results. The first model, namely the bosonic Kondo lattice model, is in the context of ultra-cold atoms in optical lattices. We found that its physics is close to that of the Bose-Hubbard model, exhibiting Mott and superfluid phases. The local coupling strengthens the insulating behaviour of the system and magnetism emerges through indirect or direct coupling between bosons. Thermal effects, inherent in experiments, are also studied. The second model, which is in the context of light-matter interaction, describes a situation of an ultra-strong coupling between spin-0 bosons (photons) and local spins 1/2 (two levels atoms) and is known as the Rabi lattice model. The phase diagram generally consists of only two phases: a coherent phase and a compressible incoherent one. The locals

Abstract:

AbstractThe possible existence of exotic spin-dependent interactions with ranges from the subatomic scale to astrophysical scales has been of great theoretical interest for the last few decades. Typically, these exotic interactions are mediated by ultralight bosons with very weak coupling strength. If they indeed exist, such long-range interactions would indicate new physics beyond the Standard Model. A wide variety of experimental tests have been made to search for novel long-range spin-dependent interactions. Most experimental searches have focused on monopole-dipole or dipole-dipole interactions that could be induced by the exchange of ultralight bosons such as axions or axionlike particles. These ultralight bosons could also provide an answer to some of the most challenging problems in modern particle physics and astronomy: for example, the strong-CP problem in quantum chromodynamics (QCD), where C represents the charge conjugate symmetry and P represents the parity symmetry, and the explanation of dark matter and dark energy. In this chapter, we discuss the theoretical motivations as well as experimental searches for exotic spin-dependent interactions mediated by ultralight bosons in recent decades. We also introduce ongoing experimental efforts, such as Axion Resonant InterAction DetectioN Experiment (ARIADNE) and the QUest for AXion (QUAX)-gsgp experiment. The high sensitivities of these tests will allow vast expansion of the discovery potential for exotic spin-dependent interactions.

Abstract:

AbstractThe light-shining-through-walls (LSW) method of searching for ultralight bosonic dark matter (UBDM) uses lasers and strong dipole magnets to probe the coupling between photons and UBDM in the presence of a magnetic field. Since these experiments take place entirely in the laboratory, they offer a unique opportunity to perform a model independent measurement of this interaction. This involves shining a high-power laser through a magnetic field toward a wall which blocks the light. The interaction between the laser and the magnetic field generates a beam of UBDM that passes through the wall. Beyond the wall is another region of strong magnetic field that reconverts the UBDM back to photons that can then be measured by a single photon detection system. The sensitivity of these kinds of experiments can be improved further by implementing optical cavities before and after the wall to amplify the power of the light propagating through the magnetic fields. This chapter gives an introduction to LSW experiments and discusses a number of interesting challenges associated with the technique.

Abstract:

This chapter introduces a select number of models of strongly interacting quantum many-particle physics and examines their basic properties. These models represent Bosonic and Fermionic systems as well as systems where magnetic moments, i.e. spins, interact. The main selection criterion has been the existence of a variant of the model that is quantum integrable using Bethe ansatz methods. After studying the Bose fluid, the Landau Fermi liquid, and the one-dimensional concept of the Luttinger liquid, it reviews some of the major models of condensed matter theory, including the Hubbard model describing itinerant magnetism, the Heisenberg model describing localized magnetism, and the Kondo model describing the interaction of a magnetic impurity and band electrons. It also presents the Rabi model and some of its descendants in order to describe the interaction of light and quantum matter in quantum optics.

Abstract:

Quantum chromodynamics the quantum gauge theory of strong interactions is presented: SU(3) being the (colour) symmetry group. The colour content of strongly interacting particles is described. Gluons, the field particles, carry colour so that they mutually interact – unlike photons. Renormalization leads to the coupling strength declining at large four momentum transfer squared q <sup>2</sup> and to binding of quarks in hadrons at small q <sup>2</sup>. The cutoff in the range of the strong interaction is shown to be due to this low q <sup>2</sup> behaviour, despite the gluon being massless. In high energy interactions, say proton-proton collisions, the initial process is a hard (high q <sup>2</sup>) parton+parton to parton+parton process. After which the partons undergo softer interactions leading finally to emergent hardrons. Experiments at DESY probing proton structure with electrons are described. An account of electroweak unification completes the book. The weak interaction symmetry group is SU<sub>L</sub>(2), L specifying handedness. This makes the electroweak symmetry U(1)⊗SUL(2). The weak force carriers, W<sup>±</sup> and Z<sup>0</sup>, are massive, which is at odds with the massless carriers required by quantum gauge theories. How the BEH mechanism resolves this problem is described. It involves spontaneous symmetry breaking of the vacuum with scalar fields. The outcome are massive gauge field particles to match the W<sup>±</sup> and Z<sup>0</sup> trio, a massless photon, and a scalar field with a massive particle, the Higgs boson. The experimental programmes that discovered the vector bosons in 1983 and the Higgs in 2012 are described, including features of generic detectors. Finally puzzles revealed by our current understanding are outlined.

Abstract:

Two-dimensional (2D) bosons can undergo a Kosterlitz-Thouless transition[1], which does not involve macroscopic occupation of a single quantum state, but which can still result in superfluidity. In addition, strongly interacting bosons subject to a random potential can also exhibit superfluidity, as in the case of charged superfluidity that occurs in high-T c superconductors. Competition between the strength of the interaction and the degree of potential disorder are among the many complicated and competing factors which determine whether superfluidity is promoted or supressed in a Bose system[2]. Strong potential disorder forces bosons to localize and can result in an insulating Bose glass phase. Alternatively, repulsive interactions among bosons act to release them from their traps, to keep their inter-particle distances as uniform as the potential allows, and to arrange the flow direction. An appropriate interaction strength can thus promote superfluidity.
