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…
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…
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…
Experimental Observation of Topological Disclination States in Lossy Electric Circuits
Jin Liu, Wei-Wu Jin, Zhao-Fan Cai +6
Topological phase transitions can be remarkably induced purely by manipulating gain and loss mechanisms, offering a novel approach to engineering topological properties. Recent the…
Non-Hermitian Skin Effect in Periodically-Driven Dissipative Ultracold Atoms
Zhao-Fan Cai, Tao Liu, Zhongmin Yang
The non-Hermitian skin effect (NHSE), featured by the collapse of bulk-band eigenstates into the localized boundary modes of the systems, is one of most striking properties in the…
