I am strongly interested in the fundamental principles of physics and the study of complex systems using theoretical and computational tools. String Theory is a fascinating and widely studied area of theoretical physics, which attempts to unify the fundamental forces of nature, including gravity, within a single, elegant framework. The weak-strong duality and quantum information perspectives are important approaches within String Theory that have led to many exciting discoveries. Studying strongly-coupled theories is indeed a challenging area of theoretical physics, as traditional analytical techniques can become increasingly difficult to apply as the strength of the interactions between particles increases. On the other hand, numerical simulations and computational methods can offer a powerful approach to exploring these complex systems and gaining insights that may not be possible through other means.

Double Field Theory is a theoretical framework that seeks to unify the traditional concepts of T-duality and general coordinate invariance in String Theory. T-duality is a symmetry of String Theory that relates different string configurations, while general coordinate invariance is a symmetry that ensures that the laws of physics remain the same regardless of how we choose to describe spacetime. In Double Field Theory, spacetime is described by a doubled geometry, which consists of both the original torus and its dual. This doubled geometry encodes the information of both position and momentum and is invariant under T-duality transformations. In Double Field Theory, spacetime is described by a doubled geometry that includes both the original torus and its dual, and this doubled geometry encodes the information of both position and momentum. By using this doubled geometry, Double Field Theory allows for a manifestly T-duality invariant framework for String Theory.
The Ryu-Takayanagi prescription is a powerful tool for studying the connection between entanglement and spacetime in the context of the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence. This correspondence is a conjectured duality between a gravitational theory in AdS spacetime and a conformal field theory on its boundary. The Ryu-Takayanagi prescription allows us to calculate the area of a co-dimension two surface in the AdS spacetime, which is proportional to the entanglement entropy of a subregion of the boundary CFT. This implies that the geometry of spacetime can emerge from the entanglement structure of the boundary theory. The study of quantum chaos is indeed an important area of research in the study of quantum information, particularly in understanding the behavior of many-body quantum systems. The out-of-time-ordered correlation function (OTOC) is a measure that characterizes the spread of Quantum Information in a system and is used to probe the onset of Chaos.
The perturbation method is a powerful tool for studying weakly coupled systems, but it becomes less effective when the system is strongly coupled. In strongly coupled systems, the perturbative expansion breaks down, and one cannot rely on small perturbations around a known solution. The study of the Quark-Gluon Plasma (QGP) is a challenging problem in Quantum Chromodynamics (QCD) is a challenging problem in QCD due to its strong coupling nature. However, recent developments in lattice QCD, a numerical technique for simulating QCD on a discrete spacetime lattice, have allowed us to study the properties of the QGP from first principles. Lattice QCD calculations provide a non-perturbative approach to studying the strong coupling regime, and it has been successful in predicting several experimental results in heavy-ion collision experiments.
