Phase diagram in 2D Fröhlich model of metal at arbitrary carriers density: pseudogap versus doping

Abstract

It is shown that in 2D system of the fermions with simplest indirect boson-induced attraction (through the Einstein phonon exchange as an example) along with the normal and superconducting phases there arises a new (called ”abnormal normal” or pseudogap) one where the absolute value of the order parameter is finite but its phase is a random quantity. It is… (More)
