1. An Exploration of Q-Systems : From Spin Chains to Low-Dimensional AdS/CFT
Abstract : The discovery of integrability in the planar limit of the AdS5/CFT4 correspondence has led to impressive progress in the study of string theory and four-dimensional N=4 Super-Yang-Mills. In particular, with the formulation of the Quantum Spectral Curve (QSC) the spectral problem is now solved. READ MORE

2. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities
Abstract : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. READ MORE

3. Exact Results in Supersymmetric Field Theories : A dissertation on the defect and deformed
Abstract : Quantum field theories (QFTs) are the most precise descriptions of the physical reality that humanity has found. Yet exact predictions are often missing as most computations are notoriously difficult to carry out. One generally resorts to perturbation theory which immediately limits the regime of validity.

4. Aspects of the Duality between Supersymmetric Yang-Mills Theory and String Theory
Abstract : This thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1-branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. READ MORE

5. Holographic Wilson Loops : Quantum String Corrections
Abstract : The gauge-string duality has been one of the most exciting areas in theoretical physics as it connects strongly coupled field theories with weakly interacting strings. The present thesis concerns the study of Wilson loops in this correspondence. READ MORE
