Localization in infinite billiards: a comparison between quantum and classical ergodicity
Sandro Graffi, Marco Lenci
Consider the non-compact billiard in the first quandrant bounded by the positive -semiaxis, the positive -semiaxis and the graph of , . Althoug…
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…
Mean-Field Approximation of Quantum Systems and Classical Limit
Sandro Graffi, Andre' Martinez, Mario Pulvirenti
We prove that, for a smooth two-body potentials, the quantum mean-field approximation to the nonlinear Schroedinger equation of the Hartree type is stable at the classical limit h…
Mean field behaviour of spin systems with orthogonal interaction matrix
Pierluigi Contucci, Sandro Graffi, Stefano Isola
For the long-range deterministic spin models with glassy behaviour of Marinari, Parisi and Ritort we prove weighted factorization properties of the correlation functions which repr…
Statistics of energy levels and zero temperature dynamics for deterministic spin models with glassy behaviour
M. Degli Esposti, C. Giardina', S. Graffi +1
We consider the zero-temperature dynamics for the infinite-range, non translation invariant one-dimensional spin model introduced by Marinari, Parisi and Ritort to generate glassy…
