低温下一般势场中运动的热分布函数

Heat distribution function for motion in a general potential at low temperature

Hans C. Fogedby, Alberto Imparato

摘要:

本文研究了低温极限下一般势场中过阻尼布朗粒子的一维运动。我们推导出传递给粒子的热量的概率分布的显式表达式。我们发现,当地的最小值的潜在产量发散边带的热量分布,除了发散的中心峰。带的位置由潜在的间隙决定。此外,我们还确定了热分布的尾部。

英文摘要:

We consider the 1D motion of an overdamped Brownian particle in a general potential in the low temperature limit. We derive an explicit expression for the probability distribution for the heat transferred to the particle. We find that the local minima in the potential yield divergent side bands in the heat distribution in addition to the divergent central peak. The position of the bands are determined by the potential gaps. We, moreover, determine the tails of the heat distribution.
