Abstract

By applying density-functional theory calculations within local and non-local approximations via properly designed density functionals we will investigate quantum phase transitions in inhomogeneous nanomaterials. Spatial inhomogeneities are a natural feature of realistic nanostructures, due to boundaries effects, the presence of impurities, confining potentials, interfaces, disorder. In our theoretical calculations we will simulate all these inhomogeneous potentials and investigate the quantum entanglement behavior. In particular, we will explore metal to insulator transitions and superfluid to insulator transitions in conventional and exotic superconductors.
