Abstract given by the source: Quantum field theory (QFT) plays a pivotal role in elucidating a wide array of physical phenomena, ranging from condensed matter systems, high-energy particle collisions in accelerators, the evolution of cosmological perturbations and high precision gravitational wave physics. Moreover, it stands as a prominent candidate for the integration of quantum theory and gravity, with the gauge gravity duality serving as a notable illustration of this potential unification. Within this framework a conformal field theory (CFT) in d dimensions is dual to a quantum gravity theory living in a d+1 dimensional space in Anti-de-Sitter, this is the essence of AdS/CFT duality. A robust mathematical framework that describes analytically physical phenomena such as confinement, chiral symmetry breaking, and the existence of a mass gap is currently lacking. Additionally, the specific field theory mechanism through which gauge/string dualities occur is not yet fully understood. Unfortunately, a considerable portion of physical systems exhibits a strongly coupled nature, eluding many conventional theoretical methods aimed at addressing these complexities or require the computation of Feynman type diagrams or integrals that are hard to harness. So to tackle these fascinating questions one needs new and powerful tools. Fortunately, a significant amount of progress has happened during the last decades to develop and explore new non-perturbative approaches to describe quantum field theories at finite coupling and as well as new methods to exploit the perturbative regime to unprecedented levels. The goal of this project is to take advantage, further develop and combine(whenever it is possible) these modern methods to draw some lessons that might help understand analytically some of the strongly coupled phenomena that occurs in nature. To this end the current proposal aims to study physical observables at finite coupling in non-perturbative quantum field theories.
