Hidden Fermi Liquid: Self-Consistent Theory for the Normal State of High-Tc Superconductors

TL;DR

This paper presents a self-consistent theory called Hidden Fermi Liquid that models the normal state of high-Tc superconductors, successfully relating various experimental observations through a transparent formalism.

Contribution

It introduces the first self-consistent, transparent theoretical framework for the normal state of cuprates based on Gutzwiller projection effects.

Findings

Relates ARPES, resistivity, and Hall angle within the theory

Generalizes to include Fermi surface topology effects

Provides a guide for experimental validation

Abstract

Hidden Fermi liquid theory explicitly accounts for the effects of Gutzwiller projection in the t-J Hamiltonian, widely believed to contain the essential physics of the high-Tc superconductors. We derive expressions for the entire "strange metal", normal state relating angle-resolved photoemission, resistivity, Hall angle, and by generalizing the formalism to include the Fermi surface topology - angle-dependent magnetoresistance. We show this theory to be the first self-consistent description for the normal state of the cuprates based on transparent, fundamental assumptions. Our well-defined formalism also serves as a guide for further experimental confirmation.
