From: Microscopic description of insulator-metal transition in high-pressure oxygen
Effect of the orbital “Zeeman” field upon pressure. (Top) LDA + DMFT results for the orbital occupations \({n}_{\sigma }^{a}\) and (bottom) the renormalized orbital splittings δ a . Notice that \({n}_{\sigma }^{y}\) jumps at the insulator-metal transition, a behavior characteristic of orbital-selective Mott transition.
