Abstract

Using an energy-momentum dispersion for Bi2Sr2CaCu2O8 obtained from angle-resolved photoelectron spectroscopy, we show that the shrinking Fermi arc model of the pseudogap is inconsistent with the Raman scattering below Tc and specific heat near T*. By simulating the quasiparticle energy dispersion curves, we show that Fermi arcs are an artifact of a T-dependent scattering rate.
