A simple theory for the cuprates: The antiferromagnetic van Hove scenario
- Florida State Univ., Tallahassee, FL (United States); and others
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 in the dispersion of the holes. Many-body effects induce anomalous quasiparticle flat bands similar to those observed in recent angle-resolved photoemission experiments. A model of weakly interacting hole quasiparticles is proposed to describe the physics of carriers in the cuprates. The model predicts superconductivity in the d{sub x{sup 2}{minus}y{sup 2}} channel, with a typical T{sub c} {approximately} 100K. The concept of {open_quotes}optimal doping{close_quotes} appears naturally in this model, as well as a large ratio 2{Delta}/kT{sub c}{approximately}5.
