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.
