             Coulomb Correlations in Real Materials

The influence of local Coulomb interactions on the electronic
properties of transition metal oxides is investigated within
the Dynamical Mean Field Theory and Quantum Monte Carlo method.
In materials such as VO_2, SrVO_3, Sr_2RuO_4 the quasi-particle
spectra exhibit correlation features which cannot be understood
within density functional theory. In particular, we discuss the
enhancement of correlation effects at surfaces, the enhancement
of correlations due to Peierls distortion, and the analogy of
'multi-gap' Mott insulators and 'multi-gap' superconductors.
