That review paper is good. You'll want to look into this review by Zee on (Fractional) Quantum Hall fluids and the field theory approach. http://arxiv.org/abs/cond-mat/9501022 Wen's book (http://www.amazon.com/Quantum-Field-Theory-Many-body-Systems/dp/019922725X) is also a good resource for many related topics though there are some quirks.
It is known from the tunneling of Cooper pairs through Josephson junctions / Squids that there are excitations in superconductors that (a) have charge exactly 2 electron charges and (b) are in a condensate. Thus, examining the oscillations in an AC Squid establishes that there are Cooper Pairs. It does not tell us about the symmetry or similar but does ...
