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…
Observation of Impurity-Induced Scale-Free Localization in a Disordered Non-Hermitian Electrical Circuit
Hao Wang, Jin Liu, Tao Liu +1
One of unique features of non-Hermitian systems is the extreme sensitive to their boundary conditions, e.g., the emergence of non-Hermitian skin effect (NHSE) under the open bounda…
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…
