  We study effects of charge self-consistency within the combination of density
functional theory (DFT; Wien2k) with dynamical mean field theory (DMFT;
w2dynamics) in a basis of maximally localized Wannier orbitals. Using the
example of two cuprates, we demonstrate that even if there is only a single
Wannier orbital with fixed filling, a noteworthy charge redistribution can
occur. This effect stems from a reoccupation of the Wannier orbital in k-space
when going from the single, metallic DFT band to the split, insulating Hubbard
bands of DMFT. We analyze another charge self-consistency effect beyond moving
charge from one site to another: the correlation-enhanced orbital polarization
in a freestanding layer of SrVO3.
