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…
Loss-induced Floquet non-Hermitian skin effect
Yaohua Li, Cuicui Lu, Shuang Zhang +1
Non-Hermitian topological systems have attracted lots of interest due to their unique topological properties when the non-Hermitian skin effect (NHSE) appears. However, the experim…
Mechanical Squeezing via Detuning-Switched Driving
Yaohua Li, An-Ning Xu, Long-Gang Huang +1
Generation of mechanical squeezing has attracted a lot of interest for its nonclassical properties, applications in quantum information, and high-sensitivity measurement. Here we p…
