Fragility of the glassy state of a directed polymer in random media: a replica approach
Marta Sales, Hajime Yoshino
We study the stability of the glassy equilibrium state of a directed polymer in random media against weak perturbations including the intriguing problem of temperature-chaos. The s…
Random energy levels and low-temperature expansions for spin glasses
M. Picco, F. Ritort, M. Sales
In a previous paper (cond-mat/0106554) we showed the existence of two new zero-temperature exponents (λand θ') in two dimensional Gaussian spin glasses. Here we introduce a novel l…
Statistics of lowest excitations in two dimensional Gaussian spin glasses
M. Picco, F. Ritort, M. Sales
A detailed investigation of lowest excitations in two-dimensional Gaussian spin glasses is presented. We show the existence of a new zero-temperature exponent lambda describing the…
Rejuvenation in the Random Energy Model
Marta Sales, Jean-Philippe Bouchaud
We show that the Random Energy Model has interesting rejuvenation properties in its frozen phase. Different `susceptibilities' to temperature changes, for the free-energy and for o…
