论文摘要
我们获得了两个在不同温度下与局部热浴相互作用的两个量子振荡器之间的热电流的分析表达。总热流分为经典和量子贡献。我们通过利用与过度阻尼政权相关的时间尺度分离来展示如何评估这两种贡献，而不必假设通常的弱耦合和马尔可夫近似值。我们发现，即使温度较高，与与系统过度阻尼动力学相关的频率尺度相比，非平凡的量子校正也可以生存。
We obtain an analytical expression for the heat current between two overdamped quantum oscillators interacting with local thermal baths at different temperatures. The total heat current is split into classical and quantum contributions. We show how to evaluate both contributions by taking advantage of the time scale separation associated with the overdamped regime, and without assuming the usual weak coupling and Markovian approximations. We find that non-trivial quantum corrections survive even when the temperatures are high compared to the frequency scale relevant for the overdamped dynamics of the system.
