Fokker-Planck动力学系统的涨落定理

Fluctuation Theorems for Systems under Fokker-Planck dynamics

A. Perez-Madrid, I. Santamaria-Holek

摘要:

研究了在保守和非保守外力作用下的布朗运动。利用布朗运动理论的热力学方法,得到了Fokker-Planck方程,并导出了局域平衡态和准平衡态的涨落定理的表达式。在局部平衡时,所得表达式与前人的结果一致.

英文摘要:

We study Brownian motion driven with both conservative and nonconservative external forces. By using the thermodynamic approach of the theory of Brownian motion we obtain the Fokker-Planck equation and derive expressions for the Fluctuation Theorem in local equilibrium and in quasi-equilibrium. In local equilibrium the expressions we obtain coincide with previous results.
