dc.descriptionThe Mott insulator LaVO$_3$ is known to become metallic if La is replaced by small concentrations of Ca. Since surface quasi-particle spectra of various perovskites are more strongly correlated than their bulk spectra, the coexistence of a metallic bulk and an insulating surface layer might be feasible. To investigate this possibility the dynamical mean field theory is used to evaluate the quasi-particle spectra in the bulk and at the surface of Ca$_x$La$_{1-x}$VO$_3$ for various Ca concentrations.
