Mri-phy/p991031 Transport in a Class of Exactly Solvable Models of Interacting Fermions


We study transport in a class of exactly solvable models of interacting fermions in one dimension. We contrast these models with models of non-interacting fermions in an AharanovBohm ring to which they are superficially similar. We introduce magnetic and non-magnetic impurities at a site, through either a weak δ-function potential or through a weak link… (More)
