Fermi blockade of the strong electron–phonon interaction in modelled optimally doped high temperature superconductors

Abstract We study how manifestations of strong electron–phonon interaction depend on the carrier concentration by solving the two-dimensional Holstein model for the spin-polarized fermions using an approximation free bold-line diagrammatic Monte Carlo method. We show that the strong electron–phonon...
