Abstract

In the context of a simple model featuring an explicit, central interaction potential, and using a standard functional-integral technique, we

as an emergent property of the many-body system. Our interaction

of the rotational symmetry is the result of an interplay between

to interactions of this type and is responsible for the existence

l=2 pairing takes place only in the BCS limit. In contrast, as the

``preformed pairs'' becomes the dominant contribution and there

We also find that the limiting value of the critical temperature

with the usual result only for l=0; for l>0, it differs in the degeneracy

on exotic pairing in the BE limit, while at the same time indicating

a particularly interesting route to pairing with l>0 in a BCS superconductor.
