摘要: We develop a systematic expansion method of physical quantities for the SK model and finite-dimensional ± J spin glasses in non-equilibrium states. The dynamical probability distribution function is derived from master equation using high temperature expansion. calculate expectation values function. theoretical curves show satisfactory agreement with Monte Carlo simulation results appropriate time regions. A comparison made dynamics theory by Coolen, Laughton Sherrington.
