Quantum Simulation of Tunable and Ultrastrong Mixed-Optomechanics
Yue-Hui Zhou, Xian-Li Yin, Jie-Qiao Liao
We propose a reliable scheme to simulate tunable and ultrastrong mixed (first-order and quadratic optomechanical couplings coexisting) optomechanical interactions in a coupled two-…
Quantum entanglement maintained by virtual excitations in an ultrastrongly-coupled-oscillator system
Jian-Yong Zhou, Yue-Hui Zhou, Xian-Li Yin +2
We study the effect of quantum entanglement maintained by virtual excitations in an ultrastrongly-coupled harmonic-oscillator system. Here, the quantum entanglement is caused by th…
Quantum thermalization and vanishing thermal entanglement in the open Jaynes-Cummings model
Li-Bao Fan, Yue-Hui Zhou, Fen Zou +3
The quantum thermalization of the Jaynes-Cummings (JC) model in both equilibrium and non-equilibrium open-system cases is sdudied, in which the two subsystems, a two-level system a…
Spectral characterization of couplings in a mixed optomechanical model
Yue-Hui Zhou, Fen Zou, Xi-Ming Fang +2
We study the spectrum of single-photon emission and scattering in a mixed optomechanical model which consists of both linear and quadratic optomechanical interactions. The spectra…
Spectrometric detection of weak forces in cavity optomechanics
Yue-Hui Zhou, Qing-Shou Tan, Xi-Ming Fang +2
We propose a spectrometric method to detect a classical weak force acting upon the moving end mirror in a cavity optomechanical system. The force changes the equilibrium position o…
