We analytically address the non-equilibrium problem of a Brownian particle in contact with a thermal reservoir by means of a non-Gaussian Langevin noise term η(t). The presence of noise kurtosis is akin to a second temperature reservoir acting on the system, and we exploit its consequences by...

Previous works have shown that time asymmetric forcing on the one hand, as well as non-Gaussian noises on the other, can separately enhance the efficiency and current of a Brownian motor. Here, we study the result of subjecting a Brownian motor to both effects simultaneously. Our results have...

The Langevin system subjected to non-Gaussian colored noise has been discussed, by using the second-order moment approach with two kinds of models for generating the noise. We have derived the effective differential equation (DE) for a variable x, from which the stationary probability...

A stochastic system with coupling between non-Gaussian and Gaussian noise terms is investigated. A general approximate Fokker–Planck equation of the system is derived through a path-integral approach. For a bistable system, the coupling λ between noise terms can induce the reentrance-like...

We study noise-induced transitions when the system is driven separately by a Gaussian colored noise and a non-Gaussian bounded noise with the same mean and stationary correlation. Clear differences in the nature of such transitions for these two cases are observed. These transitions are shown to...
