Research
Our group focuses on theoretical studies at the intersection of quantum many-body physics and quantum optics. In particular, we have studied physics of open and out-of-equilibrium systems, where quantum systems interact with external world and thus feature nonunitary dynamics. We have so far employed the ideas/methods of field theory, renormalization group, and topology as well as variational approach, Bayesian inference, and reinforcement learning. We are also interested in physical phenomena in the corresponding classical systems as well as their potential applications. More recently, we are studying applications/understanding of machine learning from a perspective of physics.

From a long-term perspective, we place value on studies that (1) provide new impetus to an area ahead of the times and (2) solve (seemingly) challenging problems by reducing them to easier (yet important) ones.
