Query: Superconducting Instability in the Periodic Anderson Model   Employing a quantum Monte Carlo simulation we find a pairing instability in
the normal state of the infinite dimensional periodic Anderson model.
Superconductivity arises from a normal state in which the screening is
protracted and which is clearly not a Fermi liquid. The phase diagram is
reentrant reflecting competition between superconductivity and Fermi liquid
formation. The estimated superconducting order parameter is even, but has nodes
as a function of frequency. This opens the possibility of a temporal node and
an effective order parameter composed of charge pairs and spin excitations.
