One-dimensional Kondo lattice model as a Tomonaga-Luttinger liquid

N. Shibata, A. Tsvelik, K. Ueda

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 mo…

Spin and charge gaps in the one-dimensional Kondo-lattice model with Coulomb interaction between conduction electrons

N. Shibata, T. Nishino, K. Ueda +1

The density-matrix renormalization-group method is applied to the one-dimensional Kondo-lattice model with the Coulomb interaction between the conduction electrons. The spin and ch…
