RESEARCH

The main focuses of my previous studies have been (i) the theory of quantum magnetism and (ii) the development of new methods for many-body systems using informational ideas. As a graduate student, I worked on the problem of how to theoretically characterize topological order in quantum spin liquids. As a posdoc, I have studied the relation between quantum entanglement and conformal field theory, and the static and dynamical properties of multiferroics and frustrated magnets.

In this project, I will work on the theory of topological order and related phenomena. Although the concept of topological order has been discussed initially in solids such as quantum Hall systems and quantum magnets, it has recently received growing interest in the context of cold atoms also. I would like to explore new topologically ordered states in solids and cold atoms.
