TLDR
In this paper, the authors considered a Brownian particle in a periodic potential under heavy damping and showed that if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed.
Abstract
We consider a Brownian particle in a periodic potential under heavy damping. The second law forbids it from displaying any net drift speed, even if the symmetry of the potential is broken. But if the particle is subject to an external force having time correlations, detailed balance is lost and the particle can exhibit a nonzero net drift speed. Thus, broken symmetry and time correlations are sufficient ingredients for transport.

Full counting statistics and fluctuation theorem for the currents in the discrete model of Feynman's ratchet

- 29 Jul 2022 - 
TL;DR: In this article , a detailed investigation on the fluctuations of the currents in the discrete model of Feynman's ratchet proposed by Jarzynski and Mazonka in 1999 is provided, with corresponding affinities determined using Schnakenberg's graph analysis.

Stochastic parametric resonance of a fractional oscillator

TL;DR: In this paper, an underdamped motion of a fractional oscillator with fluctuating eigenfrequency subjected to an internal additive fractional noise is investigated, and the exact formula for the variance of the output signal in the long-time limit is derived.

The Fokker-Planck Equation: Methods of Solution and Applications

Hannes Risken
TL;DR: In this paper, the Fokker-Planck Equation for N Variables (FPE) was extended to N = 1 variable and N = 2 variables, where N is the number of variables in the system.
