Metal-insulator phase diagram and orbital selectivity in three-orbital models with rotationally invariant Hund coupling
Metal-insulator phase diagram and orbital selectivity in three-orbital models with rotationally invariant Hund coupling
A three-band model containing the essential physics of transition-metal oxides with partially filled ${t}_{2g}$ shells is solved in the single-site dynamical mean-field approximation, using the full rotationally invariant Slater-Kanamori interactions. We compute the metal-Mott insulator phase diagram in the space of chemical potential and interaction strength, determine the response of …
