Spin-Orbit Coupling and Electronic Correlations in Sr2RuO4

> Full text via publisher
We investigate the interplay of spin-orbit coupling (SOC) and electronic correlations driven by the Hund's rule coupling in Sr2RuO4 using dynamical mean-field theory. We find that SOC does not affect the correlation-induced renormalizations, which validates the Hund's metal nature of ruthenates even in the presence of the sizeable SOC relevant to these materials. Nonetheless, SOC is found to change significantly the electronic structure at k-points where a degeneracy applies in its absence. We explain why these two observations are consistent with one another, and calculate the effects of SOC on the correlated electronic structure, obtaining excellent agreement with experiments.
