One-dimensional Kondo lattice model as a Tomonaga-Luttinger liquid
arXiv:cond-mat/9702124 · doi:10.1103/PhysRevB.56.330
Abstract
Arguments are presented that in the one-dimensional Kondo lattice model f-electron spins participate in filling of the Fermi sea. It is shown that in its paramagnetic phase this model belongs to the spin-1/2 Tomonaga-Luttinger liquid universality class. The ratio of the spin and charge velocities v_s/v_c and K_c are estimated to be of the order of (T_K/E_F)^{1/2}.
