Solution of 'Solvable model of a spin glass'

Abstract

The Sherrmgton-Kirkpatrick model of a spin glass is solved by a mean field technique which is probably exact in the limit of infinite range interactions. At and above T _c the solution is identical to that obtained by Sherrington and Kirkpatrick (1975) using the n → O replica method, but below T _c the new result exhibits several differences and remains physical down to T = 0.
