Equilibrium Behavior of the Spin-Glass Ordered Phase

A phenomenological theory of the ordered phase of short range Ising spin glasses is developed in terms of droplet excitations and presented in some detail. These excitations have free energies with a broad distribution whose characteristics magnitude grows with length scale L as L sup theta. A small fraction of droplets of all scales are thermally active; these dominate much of the physics. The mean square correlation functions are found to decay with distance as 1/r sup theta for all T
