Absence of the Mott transition in infinite dimensions
Kurt Fischer
It is shown that the half filled Hubbard model does not display the Mott metal-insulator transition, in the limit of infinite dimensions. The proposed transition on the Bethe latti…

Absence of two energy scales in the two-impurity Kondo model
Kurt Fischer
It is believed that the successive antiferromagnetic scattering of the conduction electrons on two magnetic impurities in a metal, induces a magnetic interaction between the impuri…

Diagrammatic method for investigating universal behavior of impurity systems
Kurt Fischer
The universal behavior of magnetic impurities in a metal is proved with the help of skeleton diagrams. The energy scales are derived from the structure of the skeleton diagrams. A…
