I am interested in nontrivial and fascinating properties of strongly correlated quantum matter.

In particular, my researches focus on quantum many-body physics out of equilibrium, based on the background of

- Strongly correlated systems

- Topological phases

- Nonequilibrium systems: Floquet theory, open quantum systems, etc.

I am mainly working on ultracold atoms, but some of my work are also related to correlated electron systems.

Past and current research topics are the following (see also my publication list):

• Kondo effect in ultracold atomic gases

  (Phys. Rev. Lett. 115, 165303 (2015) / Phys. Rev. B 96, 155133 (2017) / Phys. Rev. Lett. 121, 203001 (2018))

• Dissipative Hubbard model: magnetism, superfluidity, and exact solution

  (Phys. Rev. Lett. 123, 123601 (2019) / Phys. Rev. Lett. 124, 147203 (2020) / Phys. Rev. Lett. 126, 110404 (2021) / Phys. Rev. Lett. 127, 055301 (2021) / arXiv:2103.13624 / Phys. Rev. Lett. 130, 063001 (2023))

• Exact eigenstates and weak ergodicity breaking in multicomponent Hubbard models

  (arXiv:2205.07235)
