Can anderson-luttinger liquid theory be considered relevant to cuprate superconductors?

Abstract

The Anderson-Luttinger liquid theory has been examined from the viewpoint of its relevance to cuprate superconductors which have special structural and electronic features. It is found that this thoery leaves behind certain questions and doubts which are examined here. The physical features enshrined in the Anderson-Luttinger liquid theory do not necessarily require spinon and holon like excitations for their expression, as such features are also found to be present in a much more reasonable theory based on a quasi Fermi liquid description.
