How Long-Range Tails Reshape Non-Hermitian Spectra
Ding Gu, Zhanpeng Fu, Yu-Min Hu +1
Exponentially decaying long-range hoppings are ubiquitous in realistic tight-binding models and are often truncated to obtain a finite-range description. We show that this approxim…
Boundary Floquet Control of Bulk non-Hermitian Systems
Yu-Min Hu, Yu-Bo Shi, Linhu Li +5
Boundary perturbations are generally irrelevant for bulk properties in the thermodynamic limit, as they are edge-confined and subextensive. We show that this expectation breaks dow…
Asymptotic Exceptional Steady States in Dissipative Dynamics
Yu-Min Hu, Jan Carl Budich
Spectral degeneracies in Liouvillian generators of dissipative dynamics generically occur as exceptional points, where the corresponding non-Hermitian operator becomes non-diagonal…
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…
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…
Periodically Driven Open Quantum Systems: Spectral Properties and Non-Equilibrium Steady States
Hao Chen, Yu-Min Hu, Wucheng Zhang +5
In this article, we investigate periodically driven open quantum systems within the framework of Floquet-Lindblad master equations. Specifically, we discuss Lindblad master equatio…
