ZONE-DIAGONAL-DOMINATED TRANSPORT IN HIGH-T-C CUPRATES

We present a Boltzmann equation analysis of the transport properties o f a model of electrons with a lifetime that is short everywhere except near the Brillouin-zone diagonals. The assumed lifetime is directly i mplied by photoemission and c-axis transport data. We find quantitativ e agreement between calculations and ac and de longitudinal and Hall r esistivity, but the predicted longitudinal magnetoresistance disagrees with experiment. A possible microscopic origin of the anomalous lifet ime is discussed. [S0163-1829(98)04038-7].
