'Inherent structures' of the +- J ising spin glass in four dimensions

摘要

We measure the "inhrent structures" of the +-J Ising glass in four dimensions (4D) and find a behavior similar to that seen for the 2D and 3D systems. We are able to determine the transition temperature from the overlap between the quenched states and the equilibrium states. We find that the transition temperature T_(sg) is 2.07+-0.05 which agrees well with the recently reported value of 2.03+-0.03 by Maranari and Zuliani. We also find that the ground state energy for the 4D spin glass is near -2.087 +-0.005, a more estimate than the value of -1.83 reported earlier.
