论文摘要
在本文中，我们表明，可以将量子气，大规模，非相互作用，难以区分的量子颗粒的集合实现为热力学机器作为能量量化的伪像，因此没有经典的类似物。这种热力学机器取决于颗粒的统计数据，化学电位和系统的空间维度。我们的详细分析从粒子统计和系统尺寸的角度来证明了量子stirling循环的基本特征，这些循环可以通过利用量子统计力学的作用来帮助我们实现所需的量子热发动机和冰箱。特别是，在一个维度上观察到费米气体的行为和bose气的行为之间的明确区别，而不是在更高的维度上观察到，这仅仅是由于其粒子统计数据的先天差异表明量子热力学标志在较低维度中的显着作用。
In this article, we show that a quantum gas, a collection of massive, non-interacting, indistinguishable quantum particles can be realized as a thermodynamic machine as an artifact of energy quantization and hence bears no classical analog. Such a thermodynamic machine depends on the statistics of the particles, the chemical potential, and the spatial dimension of the system. Our detailed analysis demonstrates the fundamental features of quantum Stirling cycles from the viewpoint of particle statistics and system dimensions that helps us to realize desired quantum heat engines and refrigerators by exploiting the role of quantum statistical mechanics. In particular, a clear distinction between the behavior of a Fermi gas and a Bose gas is observed in one dimension than in higher dimensions, solely due to the innate differences in their particle statistics indicating the conspicuous role of a quantum thermodynamic signature in lower dimensions.
