Magnetic properties of spin glasses in a new mean field theory

G Parisi

Show affiliations


The magnetic properties of spin glasses are studied in a recently proposed mean field theory; in this approach the replica symmetry is broken and the order parameter is a function (q(x)) on the interval 0-1. Exact results at the critical temperature and approximated results at all the temperatures are derived. The comparison with the computer simulations is briefly presented.
