HIGH-TEMPERATURE DYNAMICS OF SPIN-GLASSES

We develop a systematic expansion method of physical quantities for th e SK model and the finite-dimensional +/-J model of spin glasses in no n-equilibrium states. The dynamical probability distribution function is derived from the master equation using a high temperature expansion . We calculate the expectation values of physical quantities from the dynamical probability distribution function, The theoretical curves sh ow satisfactory agreement with Monte Carlo simulation results in the a ppropriate temperature and time regions. A comparison is made with the results of a dynamics theory by Goolen, Laughton and Sherrington.
