"On the Complex Behavior of Disordered Models in a Field"

Abstract:
I will discuss several recent results, both numerical and analytical,
regarding disordered models in external field, focusing mainly on
random field ferromagnetic models and spin glasses in a field. I will
mainly treat models with Ising variables, but also some new results
on XY models will be presented.
Exact analytical results are derived for models defined on random
graphs under the Bethe approximation, while numerical results are
obtained via large scale Monte Carlo simulations for finite dimensional
models and via improved message passing algorithms for models on
  random graphs.
