Equilibrium magnetization of a spin glass : is mean-field theory valid ?
2014 Measurement of field cooled magnetization of a AgMn 10.6 % alloy as a function of temperature between 4.2 K and 50 K and magnetic field from 26 to 9 000 gauss is performed in order to link the low field and high field regimes of a spin glass. This can possibly help to define a phase diagram in the (H, T) plane as proposed by De Almeida and Thouless and Parisi and Toulouse. A closer investi...
متن کاملMean field theory of a quantum heisenberg spin glass
A full mean-field solution of a quantum Heisenberg spin-glass model is presented in a large- N limit. A spin-glass transition is found for all values of the spin S. The quantum critical regime associated with the quantum transition at S = 0 and the various regimes in the spin-glass phase at high spin are analyzed. The specific heat is shown to vanish linearly with temperature. In the spin-glass...
متن کاملMathematical Aspects of Mean Field Spin Glass Theory
A comprehensive review will be given about the rich mathematical structure of mean field spin glass theory, mostly developed, until now, in the frame of the methods of theoretical physics, based on deep physical intuition and hints coming from numerical simulation. Central to our treatment is a very simple and yet powerful interpolation method, allowing to compare different probabilistic scheme...

متن کاملOn the mean-field spin glass transition
In this paper we analyze two main prototypes of disordered mean-field systems, namely the Sherrington-Kirkpatrick (SK) and the Viana-Bray (VB) models, to show that, in the framework of the cavity method, the transition from the annealed regime to a broken replica symmetry phase can be thought of as the failure of the saturability property (detailed explained along the paper) of the overlap fluc...
