The pseudogap ground state in high temperature superconductors
arXiv:0803.1884 · doi:10.1103/PhysRevB.78.140506
Abstract
By re-examining recently-published data from angle-resolved photoemission spectroscopy we demonstrate that, in the superconducting region of the phase diagram, the pseudogap ground state is an arc metal. This scenario is consistent with results from Raman spectroscopy, specific heat and NMR. In addition, we propose an explanation for the "Fermi pockets" inferred from quantum oscillations in terms of a pseudogapped bilayer Fermi surface.
