New loop expansion for the Random Magnetic Field Ising Ferromagnets at zero temperature
Maria Chiara Angelini, Carlo Lucibello, Giorgio Parisi +2
We apply to the Random Field Ising Model at zero temperature (T= 0) the perturbative loop expansion around the Bethe solution. A comparison with the standard epsilon-expansion is m…

The Random Fractional Matching Problem
Carlo Lucibello, Enrico M. Malatesta, Giorgio Parisi +1
We consider two formulations of the random-link fractional matching problem, a relaxed version of the more standard random-link (integer) matching problem. In one formulation, we a…
