论文摘要
与两种不同的本本基载体组的叠加相关的量子相干性在热力学中被认为是必不可少的。发现连贯的因素可以通过在系统密度算子和哈密顿量的基础向量中写入可观察物作为扩展来确定。我们揭示了连贯性在有限的热力学过程中的作用，例如旋转进动和光子的自发发射。结果表明，自旋进动和自发发射过程中的热量主要是由相干产生的。
Quantum coherence associated with the superpositions of two different sets of eigenbasis vectors has been regarded as essential in thermodynamics. It is found that coherent factors can be determined by writing observables as an expansion in the basis vectors of the systemic density operator and Hamiltonian. We reveal the roles of coherence in finite-time thermodynamic processes, such as the spin precession and the spontaneous emission of a photon. Results show that the work in the spin precession and the heat in the spontaneous emission process are mainly generated by coherence.
