Topological holographic quench dynamics in a synthetic dimension
Danying Yu, Bo Peng, Xianfeng Chen +2
The notion of topological phases extended to dynamical systems stimulates extensive studies, of which the characterization of non-equilibrium topological invariants is a central is…
Additivity of Röntgen term and recoil-induced correction to spontaneous emission rate
Anwei Zhang, Danying Yu
For a moving atom, the spontaneous emission rate is modified due to the contributions from two factors, the Röntgen interaction term and the recoil effect induced by the emitted ph…
Noise-induced temporal regularity and signal amplification in an optomechanical system with parametric instability
Danying Yu, Min Xie, Yanbei Cheng +1
Noise usually has an unwelcome influence on system performance. For instance, noise inevitably affects the low-frequency mechanical freedom in optomechanical experiments. However,…
Pulse-regulated single-photon generation via quantum interference in a nonlinear nanocavity
Yuyi Yan, Yanbei Cheng, Shengguo Guan +2
A scalable on-chip single-photon source at telecommunications wavelengths is an essential component of quantum communication networks. In this work, we numerically construct a puls…
