Non-Hermitian reshaping of high-order Landau modes
Zhihao Wang, Jie Jiang, Yanji Zheng +6
When charged particles are subjected to strong magnetic fields, they form discrete energy levels known as Landau levels. The Landau levels consist of a series of degenerate states…
Open-system analogy of Berry conjecture
Yaohua Li, Yunhan Wang, Yong-Chun Liu
Berry conjecture is central to understanding quantum chaos in isolated systems and foundational for the eigenstate thermalization hypothesis. Here we establish an open-system analo…
General theory for geometry-dependent non-Hermitian bands
Chenyang Wang, Jinghui Pi, Qinxin Liu +2
In two- and higher-dimensional non-Hermitian lattices, systems can exhibit geometry-dependent bands, where the spectrum and eigenstates under open boundary conditions depend on the…
Revealing spontaneous symmetry breaking in continuous time crystals
Yuanjiang Tang, Chenyang Wang, Bei Liu +7
Spontaneous symmetry breaking plays a pivotal role in physics ranging from the emergence of elementary particles to the phase transitions of matter. The spontaneous breaking of con…
Non-Hermitian skin effect and nonreciprocity induced by dissipative couplings
Xinyao Huang, Yaohua Li, Guo-Feng Zhang +1
We study the mechanism for realizing non-Hermitian skin effect (NHSE) via dissipative couplings, in which the left-right couplings have equal strengths but the phases do not satisf…
Time Crystal in a Single-mode Nonlinear Cavity
Yaohua Li, Chenyang Wang, Yuanjiang Tang +1
Time crystal is a class of non-equilibrium phases with broken time-translational symmetry. Here we demonstrate the time crystal in a single-mode nonlinear cavity. The time crystal…
Quantum Signatures of Topological Phase in Bosonic Quadratic System
Yaohua Li, Yong-Chun Liu
Quantum entanglement and classical topology are two distinct phenomena that are difficult to be connected together. Here we discover that an open bosonic quadratic chain exhibits t…
