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…
