Overdoped cuprates

WebThe two-band memory-function conductivity formula is derived from the quantum kinetic equation in the pseudogap state of underdoped cuprates. The conduction electrons are described by using the adiabatic version of the nested Fermi liquid model, and the effects of Mott correlations are taken into account phenomenologically. WebAug 14, 2024 · The superconductivity in cuprates emerges with carrier doping to an antiferromagnetic (AF) Mott insulator (1, 2).In the half-filled insulating state, the top of the occupied band with convex upward is located at the (π/2, π/2) point of the Brillouin zone (3, 4).Hole-doping is expected to shift the Fermi energy so that it crosses the lower Hubbard …
