Abstract: This thesis encompass a series of studies on methods and models for electron systems with local interactions, relevant for correlated materials. The first study focus on the canonical model for local correlation, the Hubbard model. Using dynamical mean field theory, the critical properties of the finite temperature end point of the metal insulator transition are determined. The issue of computing real frequency spectral functions is also addressed through the development of the novel method, dis... more
