Abstract
In this work, a multichannel Kondo lattice model is studied in the thermodynamic limit. The conduction band is described by a constant hopping amplitude between any pair of lattice sites. For this system, we have obtained the exact thermodynamical properties and the ground state energies. In the limit of strong interaction between the electrons and the impurity spins, the wavefunctions take the Jastrow product form.
