We consider the power adiabatic stroke of the Otto optomechanical heat engine introduced in Phys. Rev. Lett. 112, 150602 (2014)PRLTAO0031-900710.1103/PhysRevLett.112.150602. We derive the maximum extractable work of both optomechanical normal modes in the minimum time while the system experiences quantum friction effects. We show that the total work done by the system in the power adiabatic stroke is optimized by a bang-bang control. The time duration of the power adiabatic stroke is of the order of the inverse of the effective optomechanical-coupling coefficient. The optimal phase-space trajectory of the Otto cycle for both optomechanical normal modes is also obtained.
我们考虑了发表于《物理评论快报》112, 150602 (2014) [PRLTAO0031 - 900710.1103/PhysRevLett.112.150602] 中的奥托光机械热机的功率绝热冲程。我们推导了在系统经历量子摩擦效应的情况下,两个光机械简正模在最短时间内可提取的最大功。我们表明,通过开 - 关控制可优化系统在功率绝热冲程中所做的总功。功率绝热冲程的持续时间约为有效光机械耦合系数的倒数。我们还得到了两个光机械简正模的奥托循环的最优相空间轨迹。
