Langevin equations with non-Gaussian thermal noise: Valid but superfluous (opens in new tab)

arXiv:2601.16114v1 Announce Type: new Abstract: We discuss the statistics of additive thermal (internal) noise in systems governed by the generalized Langevin equation with linear dissipation. To assess the equation's validity, it is common to assume that the system is ergodic and to verify that solutions approach correct equilibrium values at asymptotically long times. In this paper, we instead consider the consistency of the generalized Langevin equation with the Jarzynski equality at fini...
