Abstract

Critical behavior of Ising spin-glass with distribution is discussed. The results are based on the high-temperature series expansion of Edwards-Anderson susceptibility in powers of w (=tanh^{2J}kT) for 2D, 3D, and 4D "cubic" lattices to orders 19, 17, and 15, respectively. The lengths of the series are comparable to the best available for the pure Ising model. While 3D and 4D systems exhibit transitions at finite temperatures, in 2D a zero-temperature transition with a power-law divergence (in inverse temperature) for the susceptibility is found. The estimates of critical temperatures and exponents are presented.
