Testo completoIn this thesis, we apply the gauge/string duality in its supergravity limit to infer some properties of field theories at strong coupling. Experiments at RHIC and at the LHC indeed suggest that the quark--gluon plasma behaves as one of the most perfect fluid ever achieved in any controlled experimental setup. Perturbative approaches fail at accounting for its properties, whereas lattice QCD methods face technical as well as conceptual difficulties in computing dynamical aspects of this new state of matter. As a result, the AdS/CFT correspondence currently is the best tool at our disposal for analytically modelling this phase of QCD. One of the contributions of this thesis amounts to deriving a stochastic Langevin equation for a heavy quark moving across a maximally supersymmetric Yang--Mills plasma at strong coupling. Even though this theory seems to describe in a surprisingly satisfactory way the high--energy, deconfined phase of QCD, it is also of much interest to try and search for a string theory dual making closer contact with QCD at lower energies. As such, the other main focus of this thesis deals with supergravity solutions of lesser supersymmetry, without conformal invariance and exhibiting confinement. We build for the first time the gravity dual to metastable states of such theories. In particular, we find the contribution from anti--branes to the inflation potential in some general scenario of string cosmology

Testo completoThe search for string theory vacuum solutions with non-trivial fluxes is of particular importance for the construction of models relevant for particle physics phenomenology. In the framework of the AdS/CFT correspondence, four-dimensional gauge theories which can be considered to descend from N = 4 SYM are dual to ten- dimensional field configurations with geometries having an asymptotically AdS_5 factor. In this Thesis, we study mass deformations that break supersymmetry (partially or entirely) on the field theory side and which are dual to type IIB backgrounds with non-zero fluxes on the gravity side. The supergravity equations of motion constrain the parameters on the gauge theory side to satisfy certain relations. In particular, we find that the sum of the squares of the boson masses should be equal to the sum of the squares of the fermion masses, making these set-ups problematic for phenomenology applications. The study of the supergravity duals for more general deformations of the conformal field theory requires techniques which go beyond the standard geometric tools. Exceptional Generalized Geometry provides a very elegant way to incorporate the supergravity fluxes in the geometry. We study AdS_5 backgrounds with generic fluxes preserving eight supercharges and we show that these satisfy particularly simple relations which admit a geometrical interpretation in the framework of Generalized Geometry. This opens the way for the systematic study of supersymmetric marginal deformations of the conformal field theory in the context of AdS/CFT

Testo completoString Theories are our most promising candidates in the goal of unifying all interactions in nature. Gravity is naturally encapsulated in all String Theories, which are ultraviolet-free from divergences. A general feature of String Theories is the number of spacetime dimensions required. This number is either 26 or 10. In any case, this requires some further modifications of the theories since the world we are living in is a priori a 4-dimensional spacetime space. One way to tackle this problem is via so-called Kaluza-Klein compactifications. The latter is a process in which some of the dimensions of the total space are made compact and small. The idea is that at our macroscopic scale and daily energy level, the effects of those "extra" dimensions are sufficiently small so we can ignore them. In this thesis we will be interested in Supergravities, obtained from a certain regime of String Theories. In those theories, additional symmetries show up in dimensional compactifications, which allow us to reformulate Supergravities into so-called Exceptional Field Theories. Let us finally remark that Supergravities are particularly important in the context of the AdS/CFT correspondence, stating the equivalence between a theory of gravity, here a Supergravity defined on an Anti-de-Sitter (AdS) background, and a Quantum Field Theory, here a Conformal Field Theory living on the boundary of the AdS previous spacetime. In the first part of the thesis, we will make general comments and use it to introduce various concepts needed throughout the thesis. In the second part of the thesis, we will show how to use Exceptional Field Theory tech- niques to compute spectra of solutions of 11-dimensional Supergravity on AdS₄ × Σ⁷ . After reviewing the state-of-the-art techniques for Kaluza-Klein spectroscopy, we will show how Exceptional Field Theory techniques can be extended to spaces with the condition of Generalized parallelizability. We will illustrate how this technology works in the case of AdS₄ × S⁷squashed solution of 11- dimensional Supergravity, for which we give a complete answer for the spectrum. We will then show a concrete realization of the AdS₄/CFT₃ correspondence, by computing the domain-wall solution of the Supergravity equations interpolating between the round and the squashed seven- sphere, which is dual to a Renormalization Group flow on the Conformal Field Theory side. This demonstrates that not only Exceptional Field Theory techniques can be used to compute spectra around Supergravities with AdS background, but it also allows us to compute quadratic couplings of Kaluza-Klein fluctuations around a domain-wall solution of Supergravity. Finally, in the last section of the thesis, we will be interested in n-point couplings in Super- gravities. In a first part, we will show how to compute cubic couplings for specific fields on AdS₅ background of IIB 10-dimensional Supergravity via a brute force calculation. After discussing the achievements made using these techniques, we will show how we can use Exceptional Field Theory techniques to efficiently compute these couplings. Not only will this prove more efficient, but it will also allow us to write the same couplings in a more compact form, to derive formulas that apply to any vacua that are Leibniz parallelizable, and also to reveal Exceptional Field Theory structures that prove long-standing conjectures. We will illustrate the power of these techniques on the example of AdS₅ background of IIB 10-dimensional Supergravity
Ciambelli, Luca. "paving the fluid road to flat holography". Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLX055/document.
Testo completoIn this thesis we discuss the limit of vanishing cosmological constant (flat limit) of the fluid/gravity correspondence, which is a macroscopic realization of the AdS/CFT. The holographic dictionary is usually implemented in a gauge(Fefferman-Graham), which does not admit a flat limit. In the hydrodynamic formulation of the boundary theory, we introduce a gauge, dubbed derivative expansion, where such a limit turns out to be smooth. In the boundary we show that this corresponds to a Carrollian limit, i.e. a limit where the speed of light vanishes. We present Carrollian hydrodynamics, together with its dual Galilean counterpart. Then, for 4 and 3 bulk dimensions, we exhibit a resummed line element, which provides an asymptotically flat bulk solution of Einsteinequations starting only from boundary (i.e. null infinity) conformal Carrollian hydrodynamic data. In 4 dimensions we exploit specific integrability conditions, which restrict the achievable class of solutions in the bulk. In 3 dimensions every boundary fluid configuration leads to an exact solution of Einstein’s equations. Bañados solutions are a subset of the solutions reached in this way. They are rigorously identified with their surface charges and the corresponding algebra. We emphasize the choice of hydrodynamic frame, often sidesteppedin holography. Finally, we focus on the formulation of AdS/CFT to encompass Weyl symmetry. This symmetry is a key ingredient of fluid/gravity but it is not naturally encoded in the usual formulation of holography. We introduce an appropriate gauge for realizing it, and analyze its far-reaching consequences

Testo completoWe introduce a framework for quantifying random matrix behavior of 2d CFTs and AdS3 quantum gravity. We present a 2d CFT trace formula, precisely analogous to the Gutzwiller trace formula for chaotic quantum systems, which originates from the SL(2, Z) spectral decomposition of the Virasoro primary density of states. An analogy to Berry's diagonal approximation allows us to extract spectral statistics of individual 2d CFTs by coarse-graining, and to identify signatures of chaos and random matrix universality. This leads to a necessary and sufficient condition for a 2d CFT to display a linear ramp in its coarse-grained spectral form factor. Turning to gravity, AdS3 torus wormholes are cleanly interpreted as diagonal projections of squared partition functions of microscopic 2d CFTs. The projection makes use of Hecke operators. The Cotler-Jensen wormhole of AdS3 pure gravity is shown to be extremal among wormhole amplitudes: it is the minimal completion of the random matrix theory correlator compatible with Virasoro symmetry and SL(2, Z)-invariance. We call this MaxRMT: the maximal realization of random matrix universality consistent with the necessary symmetries. Completeness of the SL(2,Z) spectral decomposition as a trace formula allows us to factorize the Cotler-Jensen wormhole, extracting the microscopic object ZRMT(τ) from the coarse-grained product. This captures details of the spectrum of BTZ black hole microstates. ZRMT(τ) may be interpreted as an AdS3 half-wormhole. We discuss its implications for the dual CFT and modular bootstrap at large central charge

Testo completoN=4 SYM theory has been drawing the attention of a lot of physicists during two last decades mainly due to the two aspects: AdS/CFT correspondence and integrability. AdS/CFT correspondence is the first precise realization of the gauge/string duality whose history starts in the 60's, when a string theory was considered as a candidate for describing the strong interactions. In 1997 Maldacena made a proposal about the duality between certain conformal field theories (CFT) and string theories defined on the product of AdS space and some compact manifold, which implies a one to one map between the observables of the gauge and string counterparts. Up to now AdS/CFT correspondence still remains a conjecture. The duality of N=4 SYM and the appropriate string counterpart is the most notable example of the AdS/CFT correspondence. One of the main obstructions to exploring it is the fact that weak coupling regime for the gauge theory is the strong coupling regime for the string theory and vice versa. Therefore as long as perturbative methods are applied, one can not compare the observables of dual counterparts directly apart from some specific cases. At this point the huge symmetry of N=4 SYM plays an important role allowing exact computation of the theory observables at least in the planar limit. This property of the theory is called integrability. The observables of the N=4 SYM are Wilson loops and correlation functions built out of gauge invariant operators. The space-time dependence of the two- and three-point correlators is fixed by the conformal symmetry up to some parameters: dimensions of the operators in the case of two-point functions and dimensions of the operators and structure constants in the case of three-point functions. It's commonly accepted to refer to the problem of finding the dimensions of the operators as the spectral problem. On the classical level the operator dimension is equal to the sum of the dimensions of the fundamental fields out of which the operator is composed. When the interaction is turned on, the conformal dimension gets quantum correction. In order to compute three-point functions, apart from the conformal dimensions of corresponding operators one needs to compute the structure constants. In CFT computation of the higher-point correlators eventually can be reduced to computation of two- and three-point functions by means of the operator product expansion. Therefore two- and three-point functions appear to be building blocks of any correlator of the theory. This thesis is devoted to computation of three-point functions and consists of two parts. In the first part we consider the general approach for computing three-point functions based on the so-called spin vertex, which is inspired from the string field theory. In the second part we consider a specific kind of three-point functions called heavy-heavy-light, which are characterized by the property that the length of one of the operators is much smaller the lengthes of other two. It happens that this kind of correlators can be considered as diagonal form factors which supposes that in this case one can apply the results obtained in the form factor theory
Zhong, Deliang. "Correlation Functions in Integrable Higher Dimensional CFTs". Thesis, Sorbonne université, 2019. http://www.theses.fr/2019SORUS433.
Testo completoIn this thesis, we study two- and higher-point correlation functions of the N = 4 super Yang-Mills theory (SYM) and its deformations. This theory and its deformations are believed to be integrable in the planar limit for any values of the coupling constant, which allow us to compute various physical quantities more efficiently. The basics of N = 4 SYM and the necessary integrability tools are reviewed in the very beginning. In part II, we review the hexagon formalism for computing structure constant in N = 4 SYM. Using the nested Bethe ansatz techniques, we investigate the structure constant of two BPS operators and one non-BPS operator in the su(1, 1|2) subsector in both weak and strong coupling limit. The weak coupling result is applied to the study of the conformal partial wave expansion of asymptotic four-point functions. At strong coupling, the result is applied to the Heavy-Heavy-Light structure constants. In part III, we focus on a particular double scaling limit of N = 4 SYM, namely the fishnet limit. The Lagrangian is obtained from the deformation process, and we present the non-renormalization theorems about it. Besides, we give the first principle proof of the Yangian symmetry for a large class of fishnet Feynman diagrams, using the famous RTT-formulation of integrability. Using the integrability techniques inherited from N = 4 SYM, we also find that the continuum limit of fishnet Feynman diagrams admit an AdS sigma model description
