Flat quasiparticle dispersion and a hidden small energy scale in the 2D t-J model
Elbio Dagotto, Alexander Nazarenko, Massimo Boninsegni
A model of weakly interacting hole quasiparticles is proposed to describe the normal state of the high temperature superconductors. The effect of strong correlations is contained i…
