A numerical investigation of the jamming transition in traffic flow on diluted planar networks
Adriano Barra, Gabriele Achler
In order to develop a toy model for car's traffic in cities, in this paper we analyze, by means of numerical simulations, the transition among fluid regimes and a congested jammed…
Criticality in diluted ferromagnet
Elena Agliari, Adriano Barra, Federico Camboni
We perform a detailed study of the critical behavior of the mean field diluted Ising ferromagnet by analytical and numerical tools. We obtain self-averaging for the magnetization a…
Critical behavior of random spin systems
Luca De Sanctis, Adriano Barra, Viola Folli
We provide a strategy to find in few elementary calculations the critical exponents of the overlaps for dilute spin glasses, in absence of external field. Such a strategy is based…
Stability properties and probability distribution of multi-overlaps in dilute spin glasses
Adriano Barra, Luca De Sanctis
We prove that the Aizenman-Contucci relations, well known for fully connected spin glasses, hold in diluted spin glasses as well. We also prove more general constraints in the same…
Positive-Overlap Transition and Critical Exponents in Mean Field Spin Glasses
Alessandra Agostini, Adriano Barra, Luca De Sanctis
In this paper we obtain two results for the Sherrington-Kirkpatrick (SK) model, and we show that they both emerge from a single approach. First, we prove that the average of the ov…
