由量子物理理论和量子统计力学计算金属中热传导的速度

Calculation of Velocity of Thermal Wave in Metals by Quantum Field Theory and Quantum Statistical Mechanics

从微观的角度出发 ,应用量子场理论和量子统计力学 ,利用金属电子 声子模型 ,通过求解热传播方程 ,来求得热传播速度 。

In this paper,with the electron_phonon model of metals,the expression of relation between heat flow density and temperature,is derived by means of quantum field theory and quantum statistical mechanics.From the expression,the velocity of thermal wave v can be given.It is found the velocity is different in the metal.
