Query: Coulomb Correlations in 4d and 5d Oxides from First Principles - or How
  Spin-Orbit Materials choose their Effective Orbital Degeneracies   The interplay of spin-orbit interactions and Coulomb correlations has become
a hot topic in condensed matter theory. Here, we review recent advances in
dynamical mean-field theory-based electronic structure calculations for
iridates and rhodates. We stress the notion of the effective degeneracy of the
compounds, which introduces an additional axis into the conventional picture of
a phase diagram based on filling and on the ratio of interactions to bandwidth.
