论文摘要
了解经典和量子相关性在工作提取中的作用是热力学中重要性的问题。我们通过考虑在封闭的量子系统中考虑的最大循环工作可提取的最大循环工作等于麦角镜来解决这个问题。因此,我们旨在识别和研究来自不同类型的初始相关性(总,经典,不和谐和纠缠相关性)的麦内氏拷贝的贡献。通过这样做,我们介绍并研究了基于麦角属的相关性量词。特别是,我们的结果表明,只有不和谐相关性始终为工作提取做出积极的贡献,而总,经典和纠缠的相关性可以减少工作提取。
Understanding the role of classical and quantum correlations in work extraction is a problem of fundamental importance in thermodynamics. We approach this problem by considering that, in closed quantum systems, the maximum cyclic work extractable is equal to the ergotropy. Thus, we aim to identify and investigate the contributions to the ergotropy coming from different kinds of initial correlations (total, classical, discord and entanglement correlations). By doing so, we have introduced and studied quantifiers of correlations which are based on ergotropy. In particular, our results suggest that only discord correlations always give a positive contribution to work extraction, while total, classical and entanglement correlations can reduce the work extraction.
