      4. My research primarily focuses on aspects of Matrix Models and their applications in understanding gauge theories and holography. In particular, concrete computations gives us a better understanding of holography in lower-dimensional setting where certain observables become exactly tractable. However, there is still a lot to learn even in lower dimensional gauge theory and gravity in their respective non-perturbative regime. Using the technology of resurgence, I intend to develop a systematic procedure to understand the non-perturbative effects of low dimensional gauge theories (such as 2D Yang-Mills), matrix models and also simple 2D gravitational theories (such as JT gravity). This will further shed light and provide is with valuable insights into the rich phase structure and free energy of various phases of these apparently simple looking theories. We will also attempt to identify the universal features which will further carry over to generic higher-dimensional theories.

      2. Non-equilibrium quantum thermodynamics

      3. Non-equilibrium quantum thermodynamics

      4. Non-equilibrium thermodynamics of open quantum system is a powerful tool to study mesoscopic systems and quantum engines. I am interested in studying the thermodynamical aspect such as work statistics of a quantum system far from equilibrium and the relation to quantum informational quantities such as entanglement propagation. Recently, I have been investigating the quantum work of integrable and chaotic many-body systems. I plan to pursue these direction further to open systems as well as the application in quantum technology such as in quantum batteries. I approach the problem by employing both analytical and numerical treatments. Many of the proposed models can be realized in state-of-the-art experiments.

      4. The study of quantum gravity is put to the test in the context of black holes. The fact that black holes are thermodynamic objects with temperature, entropy, and the ability to emit thermal radiation—a discovery made by J. Bekenstein and S. Hawking—gives us a clear direction for understanding black holes and their microscopic quantum structure. My research focuses on investigating the thermodynamics of black holes as they emerge from string theory. By using deformed supergravities and the higher derivative supersymmetric actions provided by the superconformal calculus, I would like to analyze the issues from both macroscopic and microscopic perspectives. Using the quantum entropy formalism given by Ashoke Sen one accurately and methodically captures the quantum effects on black hole entropy, some of the approaches enable us to give string theory with precise tests as a contender for a theory of quantum gravity. In the future, I will continue to research distinct thermodynamic characteristics of extended objects or black holes in various ensembles.

      3. Quantum Information in Condensed Matter Physics and Field Theory

      4. I am interested in applying ideas from quantum information, in particular entanglement entropy, to the study of condensed matter physics and quantum field theory, with an emphasis on non-equilibrium phenomena like quantum chaos and Floquet physics. In previous work, I have used information scrambling to characterize quantum chaos in many-body systems. Lately, I have turned my attention to the studying entanglement dynamics in spatially inhomogeneous quenches. Another direction I have been working on is the study of topological defects in Floquet systems. I plan to continue to explore these directions as well as other topics involving the application of quantum information concepts to condensed matter physics and quantum field theory.

      4. Evolutionary game theory is a theory for explaining cooperation in populations in various fields, including social science and biology etc. I have been working in evolutionary game theory, focusing on computational inference and how uncertainty affects social cooperation. Another interest is social reputation's role in the emergence and stability of cooperative societies.

      3. Non-equilibrium quantum many-body systems

      4. My primary research interest is in non-equilibrium quantum many-body systems and understanding the associated exotic phases of matter. I am pursuing this goal along a number of different lines, including transport processes in ultra-cold atomic gases, dissipative open quantum systems and the dynamics of quantum magnets. In general, I employ a combination of analytical and numerical tools, and my work is often motivated by real experiments. Recently, I have been considering the effect of interactions in open quantum systems with non-reciprocal dynamics that display a diverging relaxation timescale via the so-called “Louivillian skin effect”. Going forward, I propose to investigate this from the perspective of universality and critical phenomena. I have also been analyzing the relaxation dynamics of multimode Bose-Einstein condensates with a view toward atomtronics, an analogue of electronics for neutral atoms. Understanding the dynamics of ultra-cold atoms and developing atomtronic devices remains an ongoing research endeavor.

      3. Emergence of Space from Loop Quantum Gravity

      4. The search for quantum gravity as a quantization of General Relativity has been carried for a long time and recently has given promising results. The research had been evolved into various tracks, which extend from the perturbative to the non-perturbative approaches. Since gravity is perturbatively non-renormalizable, the non-perturbative approaches have the advantage to avoid the problem. They could be broadly categorized into two main branches: the string and non-string approach. One of the candidates of the non-string approach is loop quantum gravity (LQG), which is standardly- based on the rigorous Dirac quantization procedure [1]. As a consequence of the theory, the spectrum of the area and volume of space are discrete, for the case of pure gravity with no matter-coupling. This indicates the existence of the quanta of space, described by spin-networks: a lattice-graph labeled by spin representations of SU(2). The graph may contain loops, where the SU(2) holonomies, describing the intrinsic curvature of a finite region of the space, are located.
