  The interface electronic structure of correlated LaTiO$_3$/SrTiO$_3$
superlattices is investigated by means of the charge self-consistent
combination of the local density approximation (LDA) to density functional
theory (DFT) with dynamical mean-field theory (DMFT). Utilizing a
pseudopotential technique together with a continuous-time quantum Monte-Carlo
approach, the resulting complex multiorbital electronic states are addressed in
a coherent fashion beyond static mean-field. General structural relaxations are
taken into account on the LDA level and cooperate with the driving forces from
strong electronic correlations. This alliance leads to an Ti($3d_{xy}$)
dominated low-energy quasiparticle peak and a lower Hubbard band in line with
photoemission studies. Furthermore correlation effects close to the
band-insulating bulk SrTiO$_3$ limit as well as the Mott-insulating bulk
LaTiO$_3$ limit are studied via realistic single-layer embeddings.
