Abstract: Abstract We investigate the physical properties of compressed gray phosphorus through density functional plus dynamical mean-field theory, showing self-doping and $$s$$ s -wave electronic structure reconstruction. At commensurate electron density, the $$3p$$ 3 p spectrum is shown to be almost unaffected by electronic correlations, however upon self-doping largely the normal and superconducting states. These findings provide a microscopic understanding of pressure-induced hole carrier superconductivity on the normal state coherence of $$s$$ s -wave superconductors with well-defined Bogoliubov quasiparticles at low temperatures. Upon internal thermalization, the $$s$$ s -wave superconducting state loses its phase coherence. Graphic abstract
