论文摘要
我们提供了一个由两个等法和两个绝热笔触组成的量子奥托发动机模型，其中绝热或压缩是通过绝热改变电势形状来实现的。在这里，我们表明，这种绝热变形可能会改变操作模式，并通过提高产量工作和效率来增强机器性能，即使有减少工作波动的优势。如果热发动机通过优化控制参数在最大功率下运行，则效率显示某些普遍行为。
We present a quantum Otto engine model consisting of two isochoric and two adiabatic strokes, where the adiabatic expansion or compression is realized by adiabatically changing the shape of the potential. Here we show that such an adiabatic deformation may alter operation mode and enhance machine performance by increasing output work and efficiency, even with the advantage of decreasing work fluctuations. If the heat engine operates under maximal power by optimizing the control parameter, the efficiency shows certain universal behavior.
