Series expansions for the Ising spin glass in general dimension.
We have developed 15th-order high-temperature series expansions for the study of the critical behavior of the Ising spin glass with nearest-neighbor exchange interactions each of which assumes the values ±J randomly. Series for the Edwards-Anderson spin-glass susceptibility (χEA) and two of its derivatives with respect to the ordering field have been evaluated for hypercubic lattices in general...
متن کاملEvidence for nonuniversal scaling in dimension-four Ising spin glasses.
The critical behavior of the Binder cumulant for Ising spin glasses in dimension four is studied through simulation measurements. Data for the bimodal interaction model are compared with those for the Laplacian interaction model. Special attention is paid to scaling corrections. The limiting infinite size value at criticality for this dimensionless variable is a parameter characteristic of a un...

متن کاملOn the 3d Ising Spin Glass
We study the 3d Ising spin glass with ±1 couplings. We introduce a modified local action. We use finite size scaling techniques and very large lattice simulations. We find that our data are compatible both with a finite T transition and with a T = 0 singularity of an unusual type.
متن کاملDyson’s equations for the (Ising) spin-glass
A complex problem is solved herej we show how to write Dyson's equations for trie (Ising) spin-glass that relate the propagator G ta trie mass operator M. In other words we are able to reduce trie inversion of an ultrametric matrix M to the solution of a Dyson's equation in ail sectors (for the replicon sectcr trie result had already been derived). It turns oui that what renders the problem tra...
