Abstract
Using a simple model of long-range impurity scattering, we illustrate how different transport and Hall relaxation rates may arise when the e lectron quasiparticle picture breaks down. We show how a broad and inc oherent spectral function requires the use of a quantum version of the Boltzmann equation. This leads to unusual transport properties, in pa rticular, a Hall relaxation rate which is independent of the quasipart icle scattering rate.
