Relaxation phenomena during non-equilibrium growth

Fluctuation relations in simple examples of non-equilibrium steady states

We discuss fluctuation relations in simple cases of non-equilibrium Langevin dynamics. In particular, we show that close to non-equilibrium steady states with non-vanishing probability currents some of these relations reduce to a modified version of the fluctuation-dissipation theorem. The latter may be interpreted as the equilibrium-like relation in the reference frame moving with the mean loc...

Non-equilibrium fluctuation dissipation relations in binary glasses

We show that at short time aging is realized in a simple model of binary glasses. We find that below the transition point the off-equilibrium correlation functions and response functions are compatible with the relations that were originally derived Cugliandolo Kurchan for generalized spin glasses.

Fluctuation relation, fluctuation theorem, thermostats and entropy creation in non equilibrium statistical Physics

The fluctuation relation is a general symmetry property of mechanical systems which should hold under the only assumption that the system motions are chaotic: it reflects the time reversal symmetry. Time reversal symmetry means a smooth isometry I of phase space which anticommutes with the time evolution map St: i.e. ISt = S−tI. Therefore the familiar operation of time reversal T or, even bette...

Strange scaling and relaxation of finite-size fluctuation in thermal equilibrium.

We numerically exhibit two strange phenomena of finite-size fluctuation in thermal equilibrium of a paradigmatic long-range interacting system having a second-order phase transition. One is a nonclassical finite-size scaling at the critical point, which differs from the prediction by statistical mechanics. With the aid of this strange scaling, the scaling theory for infinite-range models conjec...
