Spiky strings and the AdS/CFT correspondence
… of semiclassical type IIB string theory on AdS3 × S1 and on pure AdS3 in the limit of large angular momentum S. We first focus on the integrability technique known as finite-gap formalism for strings in AdS3 × S1, leading to the definition of a hyperelliptic Riemann surface, the spectral …

Zero sound modes in the AdS/CFT correspondence
… living around the charged black hole of an AdS/CFT spacetime. In particular, we show that these bulk modes cause corresponding singularities in the correlation functions of boundary gauge fields. Possible implications for the study of non-Fermi liquids are discussed.

Bubble nucleation in finite-density gauge theory using the AdS/CFT correspondence
… and the anti de-Sitter/conformal field theory (AdS/CFT) correspondence. Lastly, we look at the rotating black brane solution and the results for the bubble nucleation.

Study of the AdS/CFT correspondence and its applications to strongly coupled phenomena
La correspondencia AdS/CFT, o también llamada dualidad holográfica, ha llegado a ser una de las herramientas más potentes para describir sistemas físicos en donde las interacciones entre sus constituyentes no se pueden describir mediante análisis perturbativo. En la presente tesis, se han examinado …

Applying AdS/CFT to many body systems
… of a scalar operator in this theory using the AdS/CFT correspondence. We describe numerical techniques for calculating the retarded Green function of the operator. The results suggest that further improvement in the robustness of the codes is needed.

Non-perturbative approaches to strongly correlated electron systems
… 1.) multi-dimensional bosonization and 2.) the AdS/CFT correspondence. Multidimensional bosonization is the generalization of bosonization to spatial dimensions larger than one. The bosonized theory is an effective field theory in terms of the bosonic particle-hole fluctuations in different …

DUALITIES IN FOUR, THREE AND TWO DIMENSIONS
… strong coupling regime. At the same time, the AdS/CFT correspondence represents a cornerstone of modern physics, as it offers a concrete and mathematically robust framework in which quantum gravity emerges from a well-defined dual description in terms of a quantum field theory. The present …

An Exploration of AdS3 Gravity as a Holographic Theory
… most successful framework for holography is the AdS/CFT correspondence, which provides a non-perturbative formulation of string theory (and other theories of quantum gravity such as JT gravity). The purpose of this thesis is two-fold. The first is to give an overview of the AdS/CFT …

Fermions at finite density in the nonrelativistic gauge/gravity duality
The AdS/CFT correspondence has provided a new tool to investigate strongly correlated systems in condensed matter physics. This thesis presents the computation of retarded fermion Green functions at finite density and zero temperature in the nonrelativistic gauge/gravity duality. We find evidence …

On hadrons and inflatons: the holography of strongly coupled processes
… twentieth century. Gauge/gravity duality (or the AdS/CFT Correspondence) translates weakly coupled supergravity to strongly coupled gauge theory. The duality is holographic in that the field theory can be considered to reside on the boundary of the bulk space that hosts the gravitational theory. …

Phase transition of a vector operator in AdS-CFT
… vector operator in finite density system through AdS-CFT correspondence. By numerically solving the wave equations of the corresponding vector field in a AdS-RN black hole background geometry, we found poles of the retarded Green's functions in momentum space, which indicate possible …

Propagation of gravitons in the shock wave geometry
… in the shock wave geometry in the context of the AdS/CFT correspondence, with the goal to uncover some constraint on the supergravity action in the AdS space. In studying the shock wave geometry in an anti-deSitter (AdS) space, I find that the functional form of the shock wave metric does not …

2D Chiral Algebras from Koszul Duality & Associativity
… use Koszul duality in a different context, the AdS/CFT correspondence, to determine the planar chiral algebra for a certain supersymmetric CFT. This provides a new and analytic method to completely determine the 2 and 3-point functions of 1/4-BPS operators in the duality. This thesis is based …

Something to do with Schrödinger spacetimes
We present a brief review of the AdS/CFT correspondence and the progress made toward building a realistic gravity/gauge theory duality for a non-relativistic conformal field theory. In particular, we highlight many of the computational tools necessary for such a program before introducing one such …

AdS3 Holography from the Worldsheet
The AdS/CFT correspondence has played a prominent role in developing our understanding of the holographic nature of quantum gravity, postulating that string theory on Anti-de Sitter (AdS) space is equivalent to a conformal field theory (CFT) on the boundary of AdS. Tractable examples in which both …

Chiral symmetry breaking transitions in holographic duals
Generalisations of the AdS/CFT Correspondence are used to study chiral symmetry breaking in dual gauge theories. We use the D3/D7 and D3/D5 systems to model both 3+1 and 2+1 dimensional, strongly coupled, gauge theories with quark fields. We show that chiral symmetry breaking is induced by either …

Black holes with a twist
… thesis we study string theory on orbifolds of AdS3. Non-extremal BTZ black holes have been shown to oer a good opportunity to study closed string tachyon condensation, as there are tachyons in the winding sector even in superstring theory. We study extremal BTZ black holes, both M = 0 and M = J …
