 | Mattis, Daniel C. | Ground state of the Kondo model | The single-impurity Kondo problem is investigated with the use of the nonperturbative Lanczos (tridiagonalization) method. We are able to obtain an explicit expression for the ground-state energy in terms of the Kondo coupling constant J. The method places no restrictions on the range of J. | Kondo model; Ground-state energy; Coupling constant | 1985-06 |
