A possible experimental test of the thermodynamic approach to granular media
D. S. Dean, A. Lefèvre
We study the steady state distribution of the energy of the Sherrington-Kirkpatrick model driven by a tapping mechanism which mimics the mechanically driven dynamics of granular me…
The number of metastable states in the generalized random orthogonal model
R. Cherrier, D. S. Dean, A. Lefèvre
We calculate the number of metastable states in the generalized random orthogonal model. The results obtained are verified by exact numerical enumeration for small systems sizes bu…
The role of the interaction matrix in mean-field spin glasses
R. Cherrier, D. S. Dean, A. Lefèvre
Mean-field models of 2-spin Ising spin glasses with interaction matrices taken from ensembles which are invariant under O(N) transformations are studied. A general study shows that…
Edwards measure and the steady state regime of a model with kinetic constraints under tapping
A. Lefèvre
We study the tapping dynamics of a one dimensional Ising model with symmetric kinetic constraints. We define and test a variant of the Edwards hypothesis that one may build a therm…
