Pseudogaps: A third peak in the fermion spectral function
Oleg Tchernyshyov ;
Date 7 Oct 1997
Journal Phys.Rev.B 57, 2728 (1998)
Subject Strongly Correlated Electrons | cond-mat.str-el
AbstractI present an exactly solvable model of a pseudogap with two zero-energy fermion modes coupled to each other by a classical source of frequency omega_0 and strength |Delta|. A suitably defined fermion propagator has an infinite number of poles at frequencies that are multiple integers of omega_0. In the adiabatic limit, omega_0 << |Delta|, the situation is qualitatively different from the static case omega_0=0: the residue of the pole at omega=0 (a remnant of the bare fermion) vanishes linearly with omega_0, a result that could not be anticipated by perturbation theory; the multiple poles of the propagator coalesce into a continuum instead of forming two single poles at +-|Delta|, which should be interpreted as inhomogeneous broadening of the Bogoliubov quasiparticles.
