The rigid rotator with Lévy noise

Cáceres, Manuel O - In: Physica A: Statistical Mechanics and its Applications 283 (2000) 1, pp. 140-145

We have used an exact functional approach to solve a plane rotator in presence of Lévy noise. The cosine relaxation has been calculated. Its non-autonomous generalization can also be solved in the context of our functional analysis.

Susceptibility and transport coefficients in a transient state on a one-dimensional lattice I. Extended linear response and diffusion

Kutner, R. - In: Physica A: Statistical Mechanics and its Applications 224 (1996) 3, pp. 558-588

In this paper (Part I) we extend the linear response analysis to calculate the complex dynamic susceptibility and the … electrolyte systems. The discussed situation differs from the one considered by the usual linear response theory since our system … are well described by the usual linear response expressions for the thermalized syste. The relation between the dynamic …
