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&gt;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&gt;0 in a BCS superconductor.
