Distinguishability Transitions in Non-Unitary Boson Sampling Dynamics
Ken Mochizuki, Ryusuke Hamazaki
We discover novel transitions characterized by distinguishability of bosons in non-unitary dynamics with parity-time () symmetry. We show that symmetry…

Band structures under non-Hermitian periodic potentials: Connecting nearly-free and bi-orthogonal tight-binding models
Ken Mochizuki, Tomoki Ozawa
We explore band structures of one-dimensional open systems described by periodic non-Hermitian operators, based on continuum models and tight-binding models. We show that imaginary…

Topological phases protected by shifted sublattice symmetry in dissipative quantum systems
Makio Kawasaki, Ken Mochizuki, Hideaki Obuse
Dissipative dynamics of quantum systems can be classified topologically based on the correspondence between the Lindbladian in the Gorini-Kossakowski-Sudarshan-Lindblad equation an…
