I am interested in exploring the distribution of classical and quantum correlations in a physical system. Entanglement is one candidate for quantum correlations, which has been considered as the reason for the emergence of spacetime. In this context, I study AdS/CFT duality, or Anti-de Sitter/Conformal Field Theory duality, which is a theoretical framework that relates two seemingly different theories: anti-de Sitter space, a curved spacetime, and conformal field theory, a quantum field theory. Specifically, I am interested in entanglement and classical correlation measures for various models of black holes in AdS/CFT correspondence. Recently, I have been involved in developments regarding multiple party entanglement measures in quantum information theory.

My research work is primarily based on holographic quantum entanglement in the context of the anti-de sitter/conformal field theory (AdS/CFT) correspondence. Quantum entanglement is a physical phenomenon in which two or more particles become entangled in such a way that the state of one particle immediately influences the state of the other, regardless of their separation. On the other hand, the AdS/CFT correspondence is a duality between a gravitational theory in an anti-de sitter space and a conformal field theory on its boundary. Some of the most important issues in theoretical physics have been resolved by studying the role of quantum entanglement in the AdS/CFT duality, especially in relation to the nature of spacetime and the interplay between gravity and quantum mechanics. It covers a vast area of physics, from strongly correlated many body systems to the black hole information loss problem in quantum field theories coupled to semi-classical gravity. Particularly, I study different entanglement and correlation measures, including entanglement entropy, entanglement negativity, reflected entropy, and others, in conformal field theories with various holographic duals.
