Comparing Different Refermionizations of Multichannel Kondo Hamiltonians
ORAL
Abstract
Following a critical revision of the procedures for bosonization and debosonization of theories with boundaries [1,2] we consider novel alternative schemes to arrive at refermionized Hamiltonians for the standard multichannel Kondo model. We compare them order by order using Green-function based perturbative expansions and discuss the results on the basis of symmetries and decoupled dynamical sectors of the original theory.
