论文摘要
我们探讨了自旋轨道耦合的玻色菌凝结物在热力学周期中的潜力。为此，我们提出了一个基于带自旋轨道和Zeeman耦合作为工作介质的冷凝物的量子热发动机。冷却和加热是通过与外部磁化介质和电磁培养基的接触来模拟的。我们检查了冷凝水基态能及其对合成旋转轨道和Zeeman耦合以及原子间相互作用的强度的依赖。然后，我们研究拟议发动机的效率。该周期具有与发动机最大效率相关的自旋轨道耦合的临界值。
We explore the potential of a spin-orbit coupled Bose-Einstein condensate for thermodynamic cycles. For this purpose we propose a quantum heat engine based on a condensate with spin-orbit and Zeeman coupling as a working medium. The cooling and heating are simulated by contacts of the condensate with an external magnetized media and demagnetized media. We examine the condensate ground state energy and its dependence on the strength of the synthetic spin-orbit and Zeeman couplings and interatomic interaction. Then we study the efficiency of the proposed engine. The cycle has a critical value of spin-orbit coupling related to the engine maximum efficiency.
