Nonreciprocity-enriched steady phases in open quantum systems
Ding Gu, Zhanpeng Fu, Zhong Wang
Nonreciprocity can profoundly alter the spectra and dynamics of open quantum systems, yet its impact on the long-time steady-state phases of matter has remained largely unexplored.…
Many-Body Non-Hermitian Skin Effect with Exact Steady States in the Dissipative Quantum Link Model
Yu-Min Hu, Zijian Wang, Biao Lian +1
We introduce a dissipative lattice gauge model that exhibits the many-body version of the non-Hermitian skin effect. The dissipative couplings between dynamical gauge fields on the…
Universal non-Hermitian transport in disordered systems
Bo Li, Chuan Chen, Zhong Wang
In disordered Hermitian systems, localization of energy eigenstates prohibits wave propagation. In non-Hermitian systems, however, wave propagation is possible even when the eigens…
Non-Bloch edge dynamics of non-Hermitian lattices
Wen-Tan Xue, Fei Song, Yu-Min Hu +1
The non-Hermitian skin effect, i.e., the localization of nominally bulk modes, not only drastically reshapes the spectral properties of non-Hermitian systems, but also dramatically…
Fragile non-Bloch spectrum and unconventional Green's function
Fei Song, Hong-Yi Wang, Zhong Wang
In non-Hermitian systems, it is a counterintuitive feature of the non-Hermitian skin effect (NHSE) that the energy spectrum and eigenstates can be totally different under open or p…
