Symmetry-protected quantization of complex Berry phases in non-Hermitian many-body systems

Shoichi Tsubota, Hong Yang, Yutaka Akagi +1

We investigate the quantization of the complex-valued Berry phases in non-Hermitian quantum systems with certain generalized symmetries. In Hermitian quantum systems, the real-valu…
