Time-dependent Ginzburg-Landau model of the spin-glass phase

Abstract

The Edwards- Anderson spin-glass phase is studied via time-dependent Ginzburg- Landau models with quenched impurities. A perturbation expansion is used to study the dynamics and statics without the use of the replica method. It is shown that the spin correlation function has a t-12 long-time tail in the spin-glass phase. © 1978 The American Physical Society.
