Algebraic Fermi from Phase Fluctuations: “Topological” Fermions, Vortex “Berryons,” and QED3 Theory of Cuprate Superconductors

M. Franz and Z. Teˇsanovic´ Institute for , , Santa Barbara, California 93106 (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 and fluctuatingARTICLES vortex- antivortex excitations. The effective action describing this model assumes the form of an anisotropic Euclidean quantum electrodynamics in ͑2 1 1͒ dimensions ͑QED3͒ and naturally generates non-Fermi d-waveliquid behavior for duality its fermionic excitations. and Theits doping reflections axis in the x -T phase diagram in emerges as a quantum critical line which regulates the low energy fermiology.
