基于微观动力学的傅立叶定律

Fourier's law based on microscopic dynamics

Abhishek Dhar, Herbert Spohn

摘要:

虽然傅立叶定律在许多物质和非常广泛的热力学参数范围内得到了经验证实,但令人信服的微观推导仍然存在困难。用目前的机器,牛顿运动方程的解可以得到高精度和相当大数量的粒子。对于简化的模型系统,人们由此对傅立叶定律的微观基础有了更深入的理解。我们报告最近的和不是最近的进展。

英文摘要:

While Fourier's law is empirically confirmed for many substances and over an extremely wide range of thermodynamic parameters, a convincing microscopic derivation still poses difficulties. With current machines the solution of Newton's equations of motion can be obtained with high precision and for a reasonably large number of particles. For simplified model systems one thereby arrives at a deeper understanding of the microscopic basis for Fourier's law. We report on recent, and not so recent, advances.
