Aging in Spin Glasses in three, four and infinite dimensions
S. Jimenez, V. Martin-Mayor, G. Parisi +1
The SUE machine is used to extend by a factor of 1000 the time-scale of previous studies of the aging, out-of-equilibrium dynamics of the Edwards-Anderson model with binary couplin…

Dynamical generation of a gauge symmetry in the Double-Exchange model
J. M. Carmona, A. Cruz, L. A. Fernandez +7
It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of…
