Orbital resolved and total LDA + DMFT density-of-states (DOS) in the normal (Δ SC = 0) and supercoducting state \(({{\rm{\Delta }}}_{SC}\ne 0)\) of solid O2. Here, the normal state LDA + DMFT solution for Δ = 0.4 eV is used as starting point towards understanging the selective modification of the excitation spectrum within the superconducting state. Notice the evolution of the superconducting gap at low energies in the electronic DOS of the p y and p z orbtials.
