Far-from-equilibrium relaxation in long-range interacting stochastic few-body systems — •Felipe Pereira-Alves and Aljaž Godec — Mathematical bioPhysics group, Max Planck Institute for Multidisciplinary Sciences, Göttingen 37077, Germany

The dynamics of non-equilibrium systems in the presence of long-range interactions still pose great challenges for theory. A paradigm for such systems is Dyson's Brownian motion, for which exact calculations of certain physical observables and correlations are feasible. In our work, we interrogate the relaxation dynamics of the Dyson model prepared by a far-from-equilibrium temperature quench. It was predicted and recently experimentally confirmed that the relaxation, in the form of heating and cooling for an optically trapping colloidal particle, is fundamentally asymmetric. Here, we investigate the corresponding dynamical regimes and underlying (a)symmetries of heating versus cooling of a Dyson chain of trapped Brownian particles interacting with a long-range logarithmic potential.
