BCS versus Overhauser pairing in dense (2+1)-dimensional QCD
Journal Article

· Physical Review D
We compare the BCS and Overhauser effect as competing mechanisms for the destabilization of the quark Fermi surface at an asymptotically large chemical potential, for the special case of 2 space and 1 time dimensions. We use the framework of perturbative one-gluon exchange, which dominates the pairing at {mu}/g{sup 2}{much_gt}1. With screening in matter, we show that in the weak coupling limit the Overhauser effect can compete with the BCS effect only for a sufficiently large number of colors. Both the BCS and the Overhauser gaps are of order g{sup 4}/{mu} in the Landau gauge.
