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 …

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.

On D-brane configurations and ADS/CFT duality
… branes appearing in relation to the AdS/CFT conjecture. After a general introductory chapter to the strings, branes and dualities, each research work appears in a separate part of the thesis (parts I, II). Conclusions are given at the end of each part. In the first part we introduce …

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.

Geometry and entanglement in AdS/CFT and beyond
… the perturbative framework to geometries beyond AdS/CFT. On the field theory we side, we discuss perturbation theory with irrelevant deformations; on the gravity side, we study cutoff AdS and D3 brane geometry. The result is not conclusive, but we believe that the framework we set up, along with …

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 …

Aspects of finite temperature field theories in Ads/CFT
… field theories at finite temperature using the AdS/CFT correspondence. I present a general proof of an "inheritance principle" satisfied by a weakly coupled SU(N) (or U(N)) gauge theory with adjoint matter on a class of compact manifolds (like S3). In the large N limit, finite temperature …

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.

Gauge/Gravity Duality: Recovering the Bulk from the Boundary using AdS/CFT
… holographic principle, within the context of the AdS/CFT Correspondence in the large t'Hooft limit, we investigate how the geometry of certain highly symmetric bulk spacetimes can be recovered given information of physical quantities in the dual boundary CFT. In particular, we use the existence of …

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 …

Analysis of supersymmetric field theories via AdS/CFT, brane setups and matrix models
N = 1 theories whose matrix model spectral curve develops Argyres-Douglas singularities are constructed. The large N expansion breaks down at the critical points with domain wall tensions scaling as a fractional power of N. However, there exist double scaling limits that are conjectured to define a …

Perturbative and non perturbative effects in the Standard Model and orbifolded ADS/CFT based theories

Robustness and infrared sensitivity of various observables in the application of AdS/CFT to heavy ion physics
