Entanglement dynamics in the many-body Hatano-Nelson model
Takahiro Orito, Ken-Ichiro Imura
The entanglement dynamics in a non-Hermitian quantum system is studied numerically and analyzed from the viewpoint of quasiparticle picture. As a concrete model, we consider a one-…

Non-Hermitian Fabry-Perot Resonances in a PT-symmetric system
Ken Shobe, Keiichi Kuramoto, Ken-Ichiro Imura +1
In non-Hermitian scattering problems the behavior of the transmission probability is very different from its Hermitian counterpart; it can exceed unity or even be divergent, since…
