我们在哈密顿量和具有最近邻耦合的相关随机模型的背景下研究热传输,并推导出一大类此类模型的温度分布的普遍规律。该定律包含一个参数 α,并且仅当 α = 1 时才是线性的。α 的值取决于能量交换机制,包括示踪粒子的运动范围及其飞行时间。
We study heat transport in the context of Hamiltonian and related stochastic models with nearest-neighbor coupling, and derive a universal law for the temperature profiles of a large class of such models. This law contains a parameter α, and is linear only when α = 1. The value of α depends on energy-exchange mechanisms, including the range of motion of tracer particles and their times of flight.
