Stability of topologically protected edge states in nonlinear quantum walks: Additional bifurcations unique to Floquet systems
Ken Mochizuki, Norio Kawakami, Hideaki Obuse
Recently, effects of nonlinearity on topologically nontrivial systems have attracted attention and the stability of topologically protected edge states has been studied for a quant…

Bulk-edge correspondence and stability of multiple edge states of a symmetric non-Hermitian system by using non-unitary quantum walks
Makio Kawasaki, Ken Mochizuki, Norio Kawakami +1
Topological phases and the associated multiple edge states are studied for parity and time-reversal symmetric non-Hermitian open quantum systems by constructing a…
