Dynamical fluctuations in an exactly solvable model of spin glasses
Abstract
In this paper we calculate the dynamical fluctuations to O0305-4470/31/8/003/img6 in the low-temperature phase of the p = 2 spherical spin-glass model. We study the long-time asymptotic regimes and we find, in a short-time-difference regime, a fluctuation dissipation relation for the four-point correlation functions. This relation can be extended to the non-equilibrium regimes introducing a function 0305-4470/31/8/003/img7 which, for time t large, varies as 0305-4470/31/8/003/img8 as in the case of the two-point functions.
