量子摩擦的非平衡热力学

Nonequilibrium Thermodynamics of Quantum Friction

Daniel Reiche, Francesco Intravaia, Jen-Tsung Hsiang, Kurt Busch, Bei-Lok Hu

摘要:

热力学原理往往看似简单,但却出奇地强大。我们展示了一个简单的规则,如非平衡稳态条件下运动原子的净能量流入和流出,可以揭示许多流行的量子摩擦理论的缺点。我们的热力学方法提供了一个指导原子光学实验的概念框架,从而突出了波动耗散关系和子系统之间的长时间相关性的重要性。我们的结果引入了开放量子系统非平衡动力学(数值)模型的相容性条件。

英文摘要:

Thermodynamic principles are often deceptively simple and yet surprisingly powerful. We show how a simple rule, such as the net flow of energy in and out of a moving atom under nonequilibrium steady state condition, can expose the shortcomings of many popular theories of quantum friction. Our thermodynamic approach provides a conceptual framework in guiding atom-optical experiments, thereby highlighting the importance of fluctuation-dissipation relations and long-time correlations between subsystems. Our results introduce consistency conditions for (numerical) models of nonequilibrium dynamics of open quantum systems.
