Description
We study the dynamics of classical disordered macroscopic models
completely isolated from the environment reproducing, in a classical
setting, the ‘quantum quench’ protocol. We use two classes of models,
distinguished by the complexity of their energy landscape. We identify
quenches after which the evolution approaches a stationary state that can
be associated to equilibrium at a single temperature (related to the
energy change during the quench), cases in which an ageing asymptotic
dynamics persists asymptotically, and quenches in which a steady state
characterised by a Generalised Gibbs Ensemble is found. In the latter case
we show that all the GGE effective temperatures can be obtained from the
standard fluctuation dissipation relation, in the frequency domain. The
parameter dependence of the asymptotic states is rationalised in terms of
dynamic phase diagrams.
