Non-quasiparticle transport and resistivity saturation: a view from the large-N limit

Electron dynamics: A new model for resistivity saturation Resistivity saturates as a function of temperature in some metals; this happens in a regime in which the usual description of a metal in terms of ballistically propagating quasiparticles does not apply. In this work Yochai Werman and co-worke...
