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…
Liouvillian topology and nonreciprocal dynamics in open Floquet chains
Florian Koch, Yu-Min Hu, Jan Carl Budich
Open quantum systems far from thermal equilibrium can exhibit remarkable physical phenomena including topological properties without a direct equilibrium counterpart. Along these l…
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…
Universal scaling of Green's functions in disordered non-Hermitian systems
Yin-Quan Huang, Yu-Min Hu, Wen-Tan Xue +1
The competition between non-Hermitian skin effect and Anderson localization leads to various intriguing phenomena concerning spectrums and wavefunctions. Here, we study the linear…
From the Quantum Breakdown Model to the Lattice Gauge Theory
Yu-Min Hu, Biao Lian
The one-dimensional quantum breakdown model, which features spatially asymmetric fermionic interactions simulating the electrical breakdown phenomenon, exhibits an exponential U(1)…
Bosonic Quantum Breakdown Hubbard Model
Yu-Min Hu, Biao Lian
We propose a bosonic quantum breakdown Hubbard model, which generalizes the Bose-Hubbard model by adding an asymmetric breakdown interaction turning one boson into two between adja…
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…
Non-Bloch band theory for non-Hermitian continuum systems
Yu-Min Hu, Yin-Quan Huang, Wen-Tan Xue +1
One of the most pronounced non-Hermitian phenomena is the non-Hermitian skin effect, which refers to the exponential localization of bulk eigenstates near the boundaries of non-Her…
Steady-state edge burst: From free-particle systems to interaction-induced phenomena
Yu-Min Hu, Wen-Tan Xue, Fei Song +1
The interplay between the non-Hermitian skin effect and the imaginary gap of lossy lattices results in the edge burst, a boundary-induced dynamical phenomenon in which an exception…
Green's functions of multiband non-Hermitian systems
Yu-Min Hu, Zhong Wang
Green's functions of non-Hermitian systems play a fundamental role in various dynamical processes. Because non-Hermitian systems are sensitive to boundary conditions due to the non…
Observation of non-Hermitian edge burst in quantum dynamics
Lei Xiao, Wen-Tan Xue, Fei Song +4
The non-Hermitian skin effect, by which the eigenstates of Hamiltonian are predominantly localized at the boundary, has revealed a strong sensitivity of non-Hermitian systems to th…
Geometric Origin of Non-Bloch PT Symmetry Breaking
Yu-Min Hu, Hong-Yi Wang, Zhong Wang +1
The parity-time (PT) symmetry of a non-Hermitian Hamiltonian leads to real (complex) energy spectrum when the non-Hermiticity is below (above) a threshold. Recently, it has been de…
Non-Hermitian Edge Burst
Wen-Tan Xue, Yu-Min Hu, Fei Song +1
We unveil an unexpected non-Hermitian phenomenon, dubbed edge burst, in non-Hermitian quantum dynamics. Specifically, in a class of non-Hermitian quantum walk in periodic lattices…
Simple formulas of directional amplification from non-Bloch band theory
Wen-Tan Xue, Ming-Rui Li, Yu-Min Hu +2
Green's functions are fundamental quantities that determine the linear responses of physical systems. The recent developments of non-Hermitian systems, therefore, call for Green's…
