过阻尼系统热中的动能效应

Effects of the kinetic energy in heat for overdamped systems

Pedro V. Paraguassú, Rui Aquino, Lucianno Defaveri, Welles A. M. Morgado

摘要:

在推导过阻尼系统的热力学时,由于速度是一个慢变量,人们忽略了动能的贡献。在本文中,我们表明,动能需要存在于热分布的计算有一个正确的对应关系之间的欠阻尼和过阻尼的情况下,这意味着速度不能完全忽略这些系统的热力学。我们这样做的详细调查的动能的效果为三个不同的系统,谐波电位,对数电位,和任意的非等温过程。

英文摘要:

In the derivation of the thermodynamics of overdamped systems, one ignores the kinetic energy contribution, since the velocity is a slow variable. In this paper, we show that the kinetic energy needs to be present in the calculation of the heat distribution to have a correct correspondence between the underdamped and overdamped cases, meaning that the velocity can not be fully ignored in the thermodynamics of these systems. We do this by investigating in detail the effect of the kinetic energy for three different systems, the harmonic potential, the logarithm potential, and an arbitrary non-isothermal process.
