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…
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…
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…
Localization-Delocalization Transitions in Non-Hermitian Aharonov-Bohm Cages
Xiang Li, Jin Liu, Tao Liu
A unique feature of non-Hermitian systems is the extreme sensitivity of the eigenspectrum to boundary conditions with the emergence of the non-Hermitian skin effect (NHSE). A NHSE…
High-order topological pumping on a superconducting quantum processor
Cheng-Lin Deng, Yu Liu, Yu-Ran Zhang +21
High-order topological phases of matter refer to the systems of -dimensional bulk with the topology of -th order, exhibiting -dimensional boundary modes and can be cha…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
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…
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…
