Dynamical spin-nematic correlation in a transverse field Ising chain with non-Hermitian Gamma interaction
Yu-Hong Yan, Ran Wang, Kun-Liang Zhang
We investigate the effect of non-Hermitian Gamma interaction on the phase transitions and magnetic correlations for the transverse field Ising chain. We demonstrate that apart from…

Dynamic manifestation of exception points in a non-Hermitian continuous model with an imaginary periodic potential
Y. T. Wang, R. Wang, X. Z. Zhang
Exceptional points (EPs) are distinct characteristics of non-Hermitian Hamiltonians that have no counterparts in Hermitian systems. In this study, we focus on EPs in continuous sys…
