From: Microscopic description of insulator-metal transition in high-pressure oxygen
Orbital-selective insulator-to-metal transition in pressurized O2. In our theory, we vary the trial orbital-splitting Δ within LDA + DMFT to simulate structural changes upon pressure. In our results for the orbital-selective metallic phase the p y (and hence, total) DOS shows a clear pseudogap around E F , corresponding to an orbital-selective, non-Fermi liquid metallic phase. Inset at the top panels show the evolution of the electronic states close to the Fermi energy.
