QMC study with parton construction finds second-order deconfined criticality between Néel antiferromagnet and d-wave superconductor, with gapless Dirac dispersion in the SC phase.
Reviews the FL* theory for cuprates using ancilla layer models and SU(2) gauge theories to explain pseudogap hole pockets of area p/8, Fermi arcs, and transitions to d-wave superconductivity and Fermi liquid behavior.
