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…
Interaction-Induced Higher-Order Topological Insulator via Floquet Engineering
Chun-Ping Su, Zhao-Fan Cai, Tao Liu
Higher-order topological insulators have attracted significant interest in both static single-particle and many-body lattice systems. While periodically driven (Floquet) higher-ord…
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…
Interaction-Induced Second-Order Skin Effect
Wen-Zheng Ling, Zhao-Fan Cai, Tao Liu
In contrast to the conventional (first-order) non-Hermitian skin effect (NHSE) in a -dimensional system with linear size , the th-order (higher-order) NHSE is characterize…
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…
Dissipation and Interaction-Controlled Non-Hermitian Skin Effects
Yang Li, Zhao-Fan Cai, Tao Liu +1
Non-Hermitian skin effects (NHSEs) have recently been extensively studied at the single-particle level. When many-body interactions become dominant, novel non-Hermitian phenomena c…
Chiral-Extended Photon-Emitter Dressed States in Non-Hermitian Topological Baths
Zhao-Fan Cai, Xin Wang, Zi-Xuan Liang +2
The interplay of quantum emitters and non-Hermitian structured baths has received increasing attention in recent years. Here, we predict unconventional quantum optical behaviors of…
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…
