论文摘要
在本文中，我们研究了基于不变性的快捷方式到绝热性允许量子加热发动机的作用和相关性。我们考虑使用Landau-Zener Hamiltonian的量子热发动机，并使用Lewis-Riesenfeld基于不变的捷径到绝热方法提高其性能。该论文探讨了成本对更好性能的重要性，探讨了其与热发动机的工作和效率的关系。我们分析了热发动机周期中涉及的非绝热统一过程的持续时间的成本变化。还讨论了获得量子热发动机的准静态性能所需的成本。我们发现，由于发动机的非绝热性而丧失的效率可以使用快捷方式恢复，甚至有可能在有限的时间下以更高的成本获得准静态性能。
In this paper, we study the role and relevance of the cost for an invariant-based shortcut to adiabaticity enabled qubit heat engine operates in a quantum Otto cycle. We consider a qubit heat engine with Landau-Zener Hamiltonian and improve its performance using the Lewis-Riesenfeld invariant-based shortcut to adiabaticity method. Addressing the importance of cost for better performance, the paper explores its relationship with the work and efficiency of the heat engine. We analyze the cost variation with the time duration of non-adiabatic unitary processes involved in the heat engine cycle. The cost required to attain the quasi-static performance of the qubit heat engine is also discussed. We found the efficiency lost due to non-adiabaticity of the engine can be revived using the shortcut method and it is even possible to attain quasi-static performance under finite time with higher cost.
