论文摘要
我们提出了一个用谐波振荡器作为工作介质的集合的量子stirting热发动机。我们表明，在给定频率下，谐波振荡器量子stirling热发动机（HO-QSHE）的效率可以在热储层温度的特定比率下最大化。在谐波振荡器的低温或同等频率限制中，Ho-QSHE的效率接近Carnot效率。此外，我们将量子量子系统中的粒子集合作为工作介质分析量子stirling热发动机。在这里，工作和效率都可以在热储层温度的特定比率下最大化。这些研究将使我们能够以最佳性能操作量子stirling热发动机。 HO-QSHE的理论研究将为其实验实现提供动力，因为大多数真实系统可以作为谐波振荡器近似，以实现平衡附近的小位移。
We propose a quantum Stirling heat engine with an ensemble of harmonic oscillators as the working medium. We show that the efficiency of the harmonic oscillator quantum Stirling heat engine (HO-QSHE) at a given frequency can be maximized at a specific ratio of the temperatures of the thermal reservoirs. In the low temperature or equivalently high frequency limit of the harmonic oscillators, the efficiency of the HO-QSHE approaches the Carnot efficiency. Further, we analyse quantum Stirling heat engine with an ensemble of particle in box quantum systems as the working medium. Here both work and efficiency can be maximized at a specific ratio of temperatures of the thermal reservoirs. These studies will enable us to operate the quantum Stirling heat engines at its optimal performance. The theoretical study of the HO-QSHE would provide impetus for its experimental realisation, as most real systems can be approximated as harmonic oscillators for small displacements near equilibrium.
