Phys. Rev. Lett. 87, 257003 (2001) [4 pages]Algebraic Fermi Liquid from Phase Fluctuations: “Topological” Fermions, Vortex “Berryons,” and QED3 Theory of Cuprate SuperconductorsSee Also: Erratum Received 26 December 2000; published 3 December 2001 Within the phase fluctuation model for the pseudogap state of cuprate superconductors we identify a novel statistical “Berry phase” interaction between the nodal quasiparticles and fluctuating vortex-antivortex excitations. The effective action describing this model assumes the form of an anisotropic Euclidean quantum electrodynamics in (2+1) dimensions (QED3) and naturally generates non-Fermi liquid behavior for its fermionic excitations. The doping axis in the x-T phase diagram emerges as a quantum critical line which regulates the low energy fermiology. © 2001 The American Physical Society URL:
