abstract = {The topology of the Fermi surface of Sr2RuO4 is well
described by local-density approximation calculations with
spin-orbit interaction, but the relative size of its
different sheets is not. By accounting for many-body effects
via dynamical mean-field theory, we show that the standard
isotropic Coulomb interaction alone worsens or does not
correct this discrepancy. In order to reproduce experiments,
it is essential to account for the Coulomb anisotropy. The
latter is small but has strong effects; it competes with the
Coulomb-enhanced spin-orbit coupling and the isotropic
Coulomb term in determining the Fermi surface shape. Its
effects are likely sizable in other correlated multiorbital
systems. In addition, we find that the low-energy
self-energy matrix—responsible for the reshaping of the
Fermi surface—sizably differs from the static Hartree-Fock
limit. Finally, we find a strong spin-orbital entanglement;
this supports the view that the conventional description of
Cooper pairs via factorized spin and orbital part might not
apply to Sr2RuO4.},
