1 | Mattis, Daniel C. | Exactly solvable model of a magnetic impurity | A slight modification of the "mixing" term in Anderson's model of a magnetic impurity produces an exactly solvable model. Results of some preliminary calculations are given, and upper and lower bounds on Anderson's model are obtained by means of the exact solutions. . | Magnetic impurity; Ground-state energy; Free energy | 1971-11 |
