Exact Ground-States for the Periodic Anderson Model in Restricted Regions of the Parameter Space

Zsolt Gulacsi

Exact localised ground-states are presented for the one- and two-dimensional periodic Anderson model at finite U > 0 in restricted regions of the parameter space, which extends from the low U to the high U regions as well. The physical properties of this phase are analysed in detail.
