论文摘要
我们得出了量子奥托发动机的随机工作的一般概率分布函数,在这些发动机中,由于有限的时间持续时间,相位和驾驶过程都是不可逆转的。对于完整的循环,可以通过分析可解决的两级系统明确获得时间依赖的功率波动,平均功率和热力学效率。我们表明,效率(或权力)与电力波动之间存在权衡。
We derive the general probability distribution function of stochastic work for quantum Otto engines in which both the isochoric and driving processes are irreversible due to finite time duration. The time-dependent power fluctuations, average power, and thermodynamic efficiency are explicitly obtained for a complete cycle operating with an analytically solvable two-level system. We show that, there is a trade-off between efficiency (or power) and power fluctuations.
