On correlations and fluctuations of time-averaged densities and currents with general time-dependence

Cai Dieball A. Godec

Abstrak

We present technical results required for the description and understanding of correlations and fluctuations of the empirical density and current as well as diverse time-integrated and time-averaged thermodynamic currents of diffusion processes with a general time dependence on all time scales. In particular, we generalize the results from Dieball and Godec (2022 Phys. Rev. Lett. 129 140601); Dieball and Godec (2022 Phys. Rev. Res. 4 033243); Dieball and Godec (2022 arXiv:2206.04034 [cond-mat.stat-mech]) to additive functionals with explicit time dependence and transient or non-ergodic overdamped diffusion. As an illustration we apply the results to two-dimensional harmonically confined overdamped diffusion in a rotational flow evolving from a non-stationary initial distribution.
