Abstract
We consider a model self-energy consisting of an isotropic Fermi liquid term and a marginal Fermi liquid term which is anisotropic over the Fermi surface, vanishing in the same directions as the superconducting gap and the pseudogap. This model self-energy gives a consistent description of experimental results from angle-dependent magnetoresistance, specific heat, de Haas–van Alphen, and measurements of the quasiparticle dispersion near the Fermi surface from photoemission. In particular, we reconcile the strongly doping-dependent anomalous scattering rate observed in angle-dependent magnetoresistance with the almost doping-independent specific heat.
