Resumen:
We study a one-dimensional electronic system with density-density interactions coupled via Kondo-exchange coupling to a chain of spin 1/2 quantum impurities. We present in detail a bosonization-refermionization solution in a particular limit, known as the Toulouse point, where the Hamiltonian writes as an effective fermionic system with quadratic interactions and multiple resonances between electronic and spin degrees of freedom.
