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…
