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
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 condensed matter theorist. I am interested in studying quantum mechanical systems with a large number of degrees of freedom and how the constituent degrees of freedom cooperate with each other to realize amazing emergent phenomena. One major direction of my work is to study electronic systems with strong interaction. Surprisingly, strongly correlated electrons in various experimental systems can sometimes (for example, fractional quantum Hall effect) be understood from collective degrees of freedom which are fundamentally different from electronic degrees of freedom. I am also interested in frustrated magnets where such fascinating physics may be realized.
My research topics include: topological order in strongly correlated systems; tensor network representation and numerical simulation; exotic quantum phase transitions.

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).
