Non-Hermitian fractional quantum Hall states
Tsuneya Yoshida, Koji Kudo, Yasuhiro Hatsugai
We demonstrate the emergence of a topological ordered phase for non-Hermitian systems. Specifically, we elucidate that systems with non-Hermitian two-body interactions show a fract…

Higher-order Topological Mott Insulators
Koji Kudo, Tsuneya Yoshida, Yasuhiro Hatsugai
We propose a new correlated topological state which we call a higher-order topological Mott insulator (HOTMI). This state exhibits a striking bulk-boundary correspondence due to el…
