The Ghirlanda-Guerra Identities
Pierluigi Contucci, Cristian Giardina'
If the variance of a Gaussian spin-glass Hamiltonian grows like the volume the model fulfills the Ghirlanda-Guerra identities in terms of the normalized Hamiltonian covariance.
Thermodynamic Limit for Mean-Field Spin Models
A. Bianchi, P. Contucci, C. Giardina'
If the Boltzmann-Gibbs state of a mean-field -particle system with Hamiltonian verifies the condition for every decomposition…
Interpolating Greedy and Reluctant Algorithms
P. Contucci, C. Giardina', C. Giberti +2
In a standard NP-complete optimization problem we introduce an interpolating algorithm between the quick decrease along the gradient (greedy dynamics) and a slow decrease close to…
Energy Landscape Statistics of the Random Orthogonal Model
M. Degli Esposti, C. Giardina', S. Graffi
The Random Orthogonal Model (ROM) of Marinari-Parisi-Ritort [MPR1,MPR2] is a model of statistical mechanics where the couplings among the spins are defined by a matrix chosen rando…
Screened Vortex Lattice Model with Disorder
C. Giardina', N. V. Priezjev, J. M. Kosterlitz
The three dimensional XY model with quenched random disorder and finite screening is studied. We argue that the system scales to model with and the resulting ef…
