From the pseudogap metal to the Fermi liquid using ancilla qubits
Ya-Hui Zhang, Subir Sachdev
Abstract
This paper paper proposes a theoretical framework to study the pseudogap metal phases in hole doped cuprates. The authors use an ancilla qubit parton theory that give rise to a fractional Fermi liquid phase with Fermi arcs .The theory also predicts a ghost Fermi surface in the critical region between the pseudogap metal and the overdoped Fermi liquid, which can be tested in future experiments at optimal doping.
