Non-Fermi Liquid States of a General Model of Copper-Oxide Metals

Abstract

A summary is given of the minimum requirements posed by experimental results on a theory of copper-oxide metals and of the recent solution of a model of copper-oxygen bonding and anti-bonding bands with the most general two-body interactions allowable by symmetry which satisfies these requirements. Several experiments were proposed to test the theory.

Universal Properties of Cuprate Superconductors: Evidence and Implications

“…Note that this scenario is not incompatible with the zoo of microscopic models, relying on competing order parameters [47][48][49][50][51][52][53][54][55][56][57]. Here it is assumed that in the doping regime where superconductivity occurs, competing fluctuations, including antiferromagnetic and charge fluctuations, can be integrated out.…”
