Manipulation of nanomechanical resonator via shaking optical frequency
Dong-Yang Wang, Cheng-Hua Bai, Shutian Liu +2
In the usual optomechanical systems, the stability of the systems severely limits those researches of the macroscopic quantum effects. We study an usual cavity optomechanical syste…
Amplitude-modulation-based atom-mirror entanglement and mechanical squeezing in a hybrid optomechanical system
Cheng-Hua Bai, Dong-Yang Wang, Shou Zhang +2
We consider a hybrid optomechanical system which is composed of the atomic ensemble and a standard optomechanical cavity driven by the periodically modulated external laser field.…
Simulating Z_2 topological insulators via a one-dimensional cavity optomechanical cells array
Lu Qi, Yan Xing, Hong-Fu Wang +2
We propose a novel scheme to simulate Z_2 topological insulators via one-dimensional (1D) cavity optomechanical cells array. The direct mapping between 1D cavity optomechanical cel…
Qubit-assisted squeezing of the mirror motion in a dissipative optomechanical cavity system
Cheng-Hua Bai, Dong-Yang Wang, Shou Zhang +1
We investigate a hybrid system consisting of an atomic ensemble trapped inside a dissipative optomechanical cavity assisted with the perturbative oscillator-qubit coupling. It is s…
Spontaneous PT symmetry breaking in non-Hermitian coupled cavities array
Yan Xing, Lu Qi, Ji Cao +5
We study the effects of the position of the passive and active cavities on the spontaneous parity-time (PT) symmetry breaking behavior in non-Hermitian coupled cavities array model…
Optomechanical cooling beyond the quantum backaction limit with frequency modulation
Dong-Yang Wang, Cheng-Hua Bai, Shutian Liu +2
In the usual optomechanical cooling, even if the system has no thermal component, it still has a quantum limit-known as the quantum backaction limit (QBL)-on the minimum phonon num…
