Tapping thermodynamics of the one-dimensional Ising model

We analyse the steady-state regime of a one-dimensional Ising model under a tapping dynamics recently introduced by analogy with the dynamics of mecha nically perturbed granular media. The idea that the steady-state regime may be described by a Rat measure over metastable states of fixed energy is te sted by comparing various steady-state time-averaged quantities in extensiv e numerical simulations with the corresponding ensemble averages computed a nalytically with this flat measure. The agreement between the two averages is excellent in all the cases examined, showing that a static approach is c apable of predicting certain measurable properties of the steady-state regi me.
