Spin-orbit coupling effects on orbital-selective correlations in a three-orbital model
Yin Chen, Yi-Heng Tian, Rong-Qiang He +1
In ruthenate materials, non-Fermi liquid (NFL) phases have been observed. We used the natural orbitals renormalization group (NORG) method as an impurity solver for dynamical mean-…
