Bulk-edge correspondence in nonunitary Floquet systems with chiral symmetry
Ken Mochizuki, Dakyeong Kim, Norio Kawakami +1
We study topological phases in one-dimensional open Floquet systems driven by chiral symmetric nonunitary time evolution. We derive a procedure to calculate topological numbers fro…

Effects of disorder on non-unitary symmetric quantum walks
Ken Mochizuki, Hideaki Obuse
symmetry, namely, a combined parity and time-reversal symmetry can make non-unitary quantum walks exhibit entirely real eigenenergy. However, it is known that the co…

Explicit definition of symmetry for non-unitary quantum walks with gain and loss
Ken Mochizuki, Dakyeong Kim, Hideaki Obuse
symmetry, that is, a combined parity and time-reversal symmetry is a key milestone for non-Hermite systems exhibiting entirely real eigenenergy. In the present work,…
