Research Interest

Nonequilibrium many-body physics in open quantum systems:

I am interested in strongly correlated phenomena in condensed matter physics, particularly in open quantum systems with ultracold atoms. Recently, I am working on many-body physics by using both analytical and numerical methods, such as Bethe ansatz, conformal field theory, and (non-Hermitian generalization of) density-matrix renormalization group analysis.

Entanglement phase diagram:

Recently, novel quantum phenomena that have no counterpart in a closed system have been observed: The measurement-induced phase transitions, which have recently attracted great interest such as in condensed matter physics and quantum information sciences. We have obtained the phase diagram in disordered quantum many-body dynamics under continuous measurement (see our paper).
