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 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.

Research Interest

My research activities focus on quantum many-body problems in condensed matters especially strongly correlated electronic systems. One major direction is to understand the physics of exotic phases of matter and the phase transitions. The areas I studied include fractional quantum Hall systems, the doped Mott insulators, the frustrated magnetic systems and the heavy fermion systems. I am also interested in the computational condensed matter methods, including density matrix renormalization group (DMRG), exact diagonalization (ED), numerical renormalization group (NRG).
