基于量子热力学过程，我们在没有引入温度概念的情况下，对卡诺循环、布雷顿循环、奥托循环、迪塞尔循环等典型热机循环进行了量子力学（QM）扩展。当这些 QM 发动机循环由限制在任意幂律陷阱中的理想气体实现时，就会发现量子绝热指数和陷阱指数之间的关系。揭示并讨论了给定 QM 发动机循环与其经典对应发动机循环的效率之间的差异和相似之处。
Based on quantum thermodynamic processes, we make a quantum-mechanical (QM) extension of the typical heat engine cycles, such as the Carnot, Brayton, Otto, Diesel cycles, etc., with no introduction of the concept of temperature. When these QM engine cycles are implemented by an ideal gas confined in an arbitrary power-law trap, a relation between the quantum adiabatic exponent and trap exponent is found. The differences and similarities between the efficiency of a given QM engine cycle and its classical counterpart are revealed and discussed.
