Research Interests

I am a theoretical physicist working on aspects of quantum field theory and gravity that help reveal the mystery of the quantum theory of gravity. Some of the subjects that I have studied include

  • Gauge/Gravity duality; its origin, generalizations, and applications
  • Symmetries and algebraic structures in quantum field theories
  • Soluble (sectors of) models of quantum gravity

 

Apart from the above topics, I am also interested in exciting developments in other related fields such as the quantum information/quantum gravity program, the nonperturbative bootstrap program, black holes and compact objects (from both the high energy physics and the astrophysics points of view), and curious connections between high energy physics and condensed matter physics.

Research Interests

I have been studying non-equilibrium physics and quantum gravity in terms of quantum entanglement:

We have proposed how to construct geometry in gravity dual of entanglement structure.

We have been studying the relation between Einstein eq. and constraint for entanglement entropy.

We have been studying thermal properties of entanglement entropy.

We have been studying how scrambling effect affects structure of entanglement.

Currently, I am strongly interested in properties of theories with strong scrambling effect in low energy limit. Also, I am strongly interested in the physics beyond AdS/CFT correspondence.

Research Interest

I am a theoretical physicist interested in a range of topics in quantum field theories and string theory, including the AdS/CFT correspondence, the conformal bootstrap, and scattering amplitudes. One of my current research programs is to develop efficient modern techniques to compute holographic correlators, and uncover various interesting hidden structures. These holographic correlators of boundary CFTs are dual to scattering amplitudes in AdS space, and exhibit many remarkable features similar to those of the flat space scattering amplitudes. I also work on the non-perturbative conformal bootstrap. Some of my recent works include developing functional methods to systematically extract constraints on the CFT data from the crossing equation. My research in this direction aims to provide analytic insights for the conformal bootstrap method.

Research Interests

My current researches focus on using conformal field theory to understand quantum gravity through the AdS/CFT correspondence. In particular, I am interested in exploring the deep underlying origin of the correspondence and its connection to novel aspects of quantum field theories, such as entanglement structures and chaotic properties.  
 
In the past, I have also been interested in understanding non-relativistic quantum field theories; application of supersymmetric mirror symmetry to understand particle-vortex duality in three dimensions; as well as AdS/CMT.
