Abstract
We explore, using a Ginzburg-Landau expansion of the free energy, theLarkin-Ovchinnikov-Fulde-Ferrell (LOFF) phase of QCD with three flavors, usingthe NJL four-fermion coupling to mimic gluon interactions. We find that, belowthe point where the QCD homogeneous superconductive phases should give way tothe normal phase, Cooper condensation of the pairs u-s and d-u is possible, butin the form of the inhomogeneous LOFF pairing.File in questo prodotto:
