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.
