On the basis of the multiorbital dynamical mean-field theory, a three-orbital Hubbard model with relativistic spin-orbit coupling (SOC) is studied at five electrons per site. The numerical calculations are performed by employing the continuous-time quantum Monte Carlo (CTQMC) method based on the strong-coupling expansion. We find that appropriately choosing bases, …
