Abstract

The Glauber dynamics of an Ising spin glass with infinite-range interactions and additional static field, h, is investigated near the freezing temperature, T f. We obtain critical slowing down at and below the de Almeida-Thouless instability line, h c(T), to order (1−T/T f) 3 with algebraic decay of the spin correlations ∼t −ν, where ν= 1 2 at T f and ν≤ 1 2 for T< T f .
