Non-Markovian dynamics of open quantum systems without rotating wave approximation
Ming-Jia Tang, Yu-Kai Wu, Ming Lyu +4
We study the non-Markovian dynamics of a damped oscillator coupled with a reservoir. We present exact formulas for the oscillator's evolution directly from the BCH formula by serie…

Improving Cooling performance of the mechanical resonator with the two-level-system defects
Tian Chen, Xiang-Bin Wang
We study cooling performance of a realistic mechanical resonator containing defects. The normal cooling method through an optomechanical system does not work efficiently due to tho…

Finite time cooling in dispersively and dissipatively coupled optomechanics
Tian Chen, Xiang-Bin Wang
The cooling performance of an optomechanical system comprising both dispersive and dissipative coupling is studied. We present a scheme to cool a mechanical resonator to its ground…
