Rigorous derivation of an effective model for periodic Schrödinger equations with linear band crossing of Dirac type
Elena Danesi
In this paper we consider a family of time-dependent 1-dimensional cubic Schrödinger equation (NLS) with periodic potential. Exploiting semiclassical scaling and multiscale analysi…

Generalized Strichartz estimates for the massive Dirac equation with critical potentials
Federico Cacciafesta, Elena Danesi, Eric Séré
In this paper we prove generalized Strichartz estimates for the massive Dirac equation in the case of two critical potential perturbations, namely the Aharonov-Bohm magnetic p…
