Observation of non-Hermitian bulk-boundary correspondence in non-chiral non-unitary quantum dynamics of single photons
Miao Zhang, Yue Zhang, Shuai Li +9
The breakdown of conventional bulk-boundary correspondence, a cornerstone of topological physics, is one of counter-intuitive phenomena in non-Hermitian systems, that is deeply roo…
Non-Hermiticity enhanced topological immunity of one-dimensional -wave superconducting chain
Min Liu, Yue Zhang, Rui Tian +5
Studying the immunity of topological superconductors against non-local disorder is one of the key issues in both fundamental researches and potential applications. Here, we demonst…
Many-body interferometry of one-dimensional integrable systems
Maksims Arzamasovs, Min Liu, Yue Zhang +4
We propose using many-body Ramsey interferometry to measure non-equilibrium correlation functions of one-dimensional (1D) integrable systems. The 1D transverse-field Ising model, w…
Experimental investigation of the uncertainty relation in pre- and postselected systems
Yue Zhang, Xinyang Che, Yuanbang Wei +5
Uncertainty principle is one of the fundamental principles of quantum mechanics. Exploring such uncertainty relations in pre- and postselected (PPS) systems, where weak measurement…
Nonlinearity-induced dynamical self-organized twisted-bilayer lattices in Bose-Einstein condensates
Rui Tian, Yue Zhang, Tianhao Wu +4
Creating crystal bilayers twisted with respect to each other would lead to large periodic supercell structures, which can support a wide range of novel electron correlated phenomen…
Anomalous symmetry protected blockade of skin effect in one-dimensional non-Hermitian lattice systems
Shuai Li, Min Liu, Yue Zhang +3
The non-Hermitian skin effect (NHSE), an anomalous localization behavior of the bulk states, is an inherently non-Hermitian phenomenon, which can not find a counterpart in Hermitia…
Non-chiral non-Bloch invariants and topological phase diagram in non-unitary quantum dynamics without chiral symmetry
Yue Zhang, Shuai Li, Yingchao Xu +7
The non-Bloch topology leads to the emergence of various counter-intuitive phenomena in non-Hermitian systems under the open boundary condition (OBC), which can not find a counterp…
Topological flat band with higher winding number in a superradiance lattice
Shuai Li, Rui Tian, Huan Wang +3
A five-level M-type scheme in atomic ensembles is proposed to generate a one-dimensional bipartite superradiance lattice in momentum space. By taking advantage of this tunable atom…
Localization-delocalization Transition in an electromagnetically induced photonic lattice
Rui Tian, Shuai Li, Maksims Arzamasovs +3
We investigate the localization-delocalization transition (LDT) in an electromagnetically induced photonic lattice. A four-level tripod-type scheme in atomic ensembles is proposed…
Chiral odd Chern number lattice supersolidity with tunable unpaired Majorana fermions in a Rydberg-dressed Fermi gas
Shuai Li, Rui Tian, Min Liu +2
There is growing interest to search the chiral Majorana fermions that could arise as the quasi-particle edge state of a two-dimensional topological state of matter. Here we propose…
