Welcome

I am a theoretical physicist. My main research area is the condensed matter theory. I am especially interested in the quantum many-body physics out of equilibrium, such as the quench states and Floquet states of topological insulators and superconductors, spacetime crystals with Lorentz symmetry, properties of spectrum and state in nonequilibrium chaotic systems, dynamical quantum phase transitions, dynamical signature of localization-delocalization transitions on incommensurate lattices, driven-dissipative phase transitions in spin models, and quantum impurity models far from equilibrium. I am also interested in the quantum measurement problem, especially the reconciliation of relativity and spontaneous collapse models.
