Quasiparticle Band Structure and Spin Excitation Spectrum of the Kondo Lattice
arXiv:1902.10442 · doi:10.1103/PhysRevB.99.085134
Abstract
A formulation of the Kondo lattice Hamiltonian in terms of bond particles is derived and solved in two different approximations. The bond particles correspond to the eigenstates of a single unit cell and are bosons for states with even electron number and fermions for states with an odd electron number. A s a check various physical quantities are calculated for the 1D Kondo insulator a nd good agreement with numerical results is obtained for J/t>1.
