Delocalization effect of the Hubbard repulsion in exact terms and two dimensions
Zsolt Gulacsi
The genuine physical reasons explaining the delocalization effect of the Hubbard repulsion U are analyzed. First it is shown that always when this effect is observed, U acts on the…

Exact Insulating and Conducting Ground States of a Periodic Anderson Model in Three Dimensions
Zsolt Gulacsi, Dieter Vollhardt
We present a class of exact ground states of a three-dimensional periodic Anderson model at 3/4 filling. Hopping and hybridization of d and f electrons extend over the unit cell of…
