Abstract
The pressure induced superconducting phase diagram is calculated for an extension of the periodic Anderson model (PAM) in the limit taking into account the effect of a nearest neighbor attractive interaction between f-electrons. We analyze the role of the chemical potential compared to several plots of the f-band density of states and we also found a superconductor-insulator transition induced by pressure when the chemical potential crosses the hybridization gap.
