Brownian dynamics: from glassy to trivial

1 MSC - Matière et Systèmes Complexes

We endow a system of interacting particles with two distinct, local, Markovian and reversible microscopic dynamics. We find that while the first, standard one, leads to glassy behavior, the other one leads to a simple exponential relaxation towards equilibrium. This finding questions the intrinsic link that exists between the underlying, thermodynamical, energy landscape, and the dynamical rules with which this landscape is explored by the system.
