Composite-State Localization Beyond the External Landscape in Non-Hermitian Quasicrystals
Tian Zhou, Xue-Bin Wang, Zhongmin Yang +1
A composite excitation need not inherit the localization behavior of its constituents. We show that an interacting non-Hermitian quasiperiodic ladder realizes a controllable and re…
Quantum batteries in coherent Ising machine
Jin-Tian Zhang, Shuang-Quan Ma, Jing-Yi-Ran Jin +2
With intensive studies of quantum thermodynamics, quantum batteries (QBs) have been proposed to store and transfer energy via quantum effects. Despite many theoretical models, deco…
Arbitrary Control of Non-Hermitian Skin Modes via Disorder and An Electric Field
Zhao-Fan Cai, Yang Li, Yu-Ran Zhang +4
The non-Hermitian skin effect (NHSE), characterized by the accumulation of a macroscopic number of bulk states at system boundaries, is a hallmark of non-Hermitian physics. However…
Quantum-Squeezing-Induced Algebraic Non-Hermitian Skin Effects and Ultra Spectral Sensitivity
Zhao-Fan Cai, Tao Liu
The well-established non-Bloch band theory predicts exponential localization of skin-mode eigenstates in one-dimensional (1D) non-Hermitian systems. Recent studies, however, have u…
Versatile Control of Nonlinear Topological States in Non-Hermitian Systems
Zhao-Fan Cai, Yu-Chun Wang, Yu-Ran Zhang +2
The non-Hermitian skin effect (NHSE) and nonlinearity can both delocalize topological modes (TMs) from the interface. However, the NHSE requires precise parameter tuning, while non…
Anderson Delocalization in Strongly Coupled Disordered Non-Hermitian Chains
Wei-Wu Jin, Jin Liu, Xin Wang +7
Disorder and non-Hermitian effects together can upend how waves localize. In a 1D disordered chain, the non-Hermitian skin effect (NHSE) can induce Anderson delocalization, defying…
