# Periodic Anderson model with d-f interaction

@article{Hagymasi2011PeriodicAM, title={Periodic Anderson model with d-f interaction}, author={Imre Hagym'asi and K. Itai and Jenő S{\'o}lyom}, journal={arXiv: Strongly Correlated Electrons}, year={2011} }

We investigate an extended version of the periodic Anderson model where an interaction is switched on between the doubly occupied d- and f-sites. We perform variational calculations using the Gutzwiller trial wave function. We calculate the f-level occupancy as a function of the f-level energy with different interaction strengths. It is shown that the region of valence transition is sharpened due to the new interaction.
