Description:
Author(s): S. Lin, X. Z. Zhang, and Z. Song In the Hermitian regime, the Berry phase is always a real number. It may be imaginary for a non-Hermitian system, which leads to amplitude amplification or attenuation of an evolved quantum state. We study the dynamics of the non-Hermitian Rice-Mele model driven by a time-dependent external field. T… [Phys. Rev. A 92, 012117] Published Mon Jul 20, 2015
