Bosonization and Refermionization of Multichannel Kondo Hamiltonians

Multichannel Kondo Hamiltonians are of interest in a wide variety of problems and have been studied using a range of techniques. Here we are interested in employing bosonization methods for these Hamiltonians. Building on the recently developed consistent framework [1,2], and using old and new guidelines for bosonization-debosonization procedure for theories with boundary degrees of freedom, we gain new insights about the refermionization of these Hamiltonians. We analyze and evaluate these using Green-function based calculations, both in and out of equilibrium.
