Many-Body Non-Hermitian Physics in the Generalized Brillouin Zone
Chaoze Lu, Chuanshu Xu, Zhenghao Yang +1
The breakdown of conventional bulk-boundary correspondence (BBC) in non-Hermitian system can be resolved by the generalized Brillouin zone (GBZ) theory. However, extending the GBZ…
Entangelment Entropy on Generalized Brillouin Zone
Zhenghao Yang, Chaoze Lu, Xiancong Lu
We investigate the entanglement properties of non-Hermitian Su-Schrieffer-Heeger (SSH) model from the perspective of the Generalized Brillouin Zone (GBZ). The non-Bloch entanglemen…
Many-body phase transitions in a non-Hermitian Ising chain
Chao-Ze Lu, Xiaolong Deng, Su-Peng Kou +1
We study many-body phase transitions in a one-dimensional ferromagnetic transversed field Ising model with an imaginary field and show that the system exhibits three phase transiti…
Many-body entanglement and spectral clusters in the extended hard-core bosonic Hatano-Nelson model
Chao-Ze Lu, Gaoyong Sun
We study many-body entanglements and spectra of the extended bosonic Hatano-Nelson model in the hard-core limit. We show that the system undergoes a phase transition from a gapless…
