Breaking mechanical dark mode via the Coulomb interaction
Jian-Song Zhang, Yuan Chen, Guang-Ling Cheng +1
We propose a method to break the dark mode of two degenerate mechanical resonators (MRs) in optomechanical systems via the Coulomb interaction. Two degenerate MRs can be cooled to…
Simultaneous cooling of degenerate mechanical modes in unresolved sideband regime via optical and mechanical nonlinearities
Shuang-Shuo Chu, Han-Qiu Zhang, Jian-Song Zhang +3
We propose a scheme to simultaneously cool multiple degenerate mechanical modes in optomechanical systems beyond the resolved sideband regime. In general, one of the main obstacles…
Large and robust mechanical squeezing of optomechanical systems in a highly unresolved sideband regime via Duffing nonlinearity and intracavity squeezed light
Jian-Song Zhang, Ai-Xi Chen
We propose a scheme to generate strong and robust mechanical squeezing in an optomechanical system in the highly unresolved sideband (HURSB) regime with the help of the Duffing non…
Large mechanical squeezing beyond 3dB of hybrid atom-optomechanical systems in highly unresolved sideband regime
Jian-Song Zhang, Ai-Xi Chen
We propose a scheme for the generation of strong mechanical squeezing beyond 3dB in hybrid atom-optomechanical systems in the highly unresolved sideband (HURSB) regime where the de…
Quantum synchronization and correlations of two qutrits in a non-Markovian bath
Jian-Song Zhang
We investigate quantum synchronization and correlations of two qutrits in one non-Markovian environment using the hierarchy equation method. There is no direct interaction between…
Enhancing quadratic optomechanical coupling via nonlinear medium and lasers
Jian-Song Zhang, Ai-Xi Chen
We propose a scheme to significantly increase quadratic optomechanical couplings of optomechanical systems with the help of a nonlinear medium and two driving lasers. The nonlinear…
