Efficient production of polar molecular Bose-Einstein condensates via an all-optical R-type atom-molecule adiabatic passage

Jing Qian, Lu Zhou, Keye Zhang +1

We propose a scheme of "-type" photoassociative adiabatic passage (PAP) to create polar molecular condensates from two different species of ultracold atoms. Due to the presence…

Efficiency limitation for realizing an atom-molecule adiabatic transfer based on a chainwise system

Jingjing Zhai, Lu Zhang, Keye Zhang +2

In a recent work we have developed a robust chainwise atom-molecule adiabatic passage scheme to produce ultracold ground-state molecules via photo-associating free atoms [J. Qian {…

Autonomous Quantum Heat Engine Enabled by Molecular Optomechanics and Hysteresis Switching

Baiqiang Zhu, Pierre Meystre, Weiping Zhang +1

By integrating molecular optomechanics with molecular switches, we propose a scheme for a molecular quantum heat engine that operates autonomously through hysteretic feedback witho…

Role reversal in a Bose-condensed optomechanical system

Keye Zhang, Pierre Meystre, Weiping Zhang

We analyze the optomechanics-like properties of a Bose-Einstein condensate (BEC) trapped inside an optical resonator and driven by both a classical and a quantized light field. We…

Quantum Optomechanical Heat Engine

Keye Zhang, Francesco Bariani, Pierre Meystre

We investigate theoretically a quantum optomechanical realization of a heat engine. In a generic optomechanical arrangement the optomechanical coupling between the cavity field and…

Work measurement in an optomechanical quantum heat engine

Ying Dong, Keye Zhang, Francesco Bariani +1

We analyze theoretically the measurement of the mean output work and its fluctuations in a recently proposed optomechanical quantum heat engine [K. Zhang {\it et al.} Phys. Rev. Le…
