涨落耗散区以外两相互作用纳米颗粒间的热交换

Heat exchange between two interacting nanoparticles beyond the fluctuation-dissipation regime

Agustin Pérez-Madrid, Luciano C. Lapas, J. Miguel Rubí

摘要:

我们发现,所观察到的非单调行为的两个纳米粒子之间的热导,当它们被带到接触起源于一个复杂的相空间动力学。在这里,它是假设,这种动力学的结果从热激活跳跃通过一个粗糙的能量景观。弛豫时间的层次结构在描述这种复杂的相空间行为中起着关键作用。我们的理论使我们能够分析接触之前和接触时的热传递。

英文摘要:

We show that the observed non-monotonic behavior of the thermal conductance between two nanoparticles when they are brought into contact is originated by an intricate phase space dynamics. Here it is assumed that this dynamics results from the thermally activated jumping through a rough energy landscape. A hierarchy of relaxation times plays the key role in the description of this complex phase space behaviour. Our theory enables us to analyze the heat transfer just before and at the moment of contact.
