Influence of finite quark chemical potentials on the three flavor LOFF phase of QCD

Abstract

Abstract We study, in the Ginzburg–Landau approximation, the Larkin–Ovchinnikov–Fulde–Ferrell (LOFF) phase of QCD with three flavors and one plane wave, including terms of order O ( 1 / μ ) . We show that the LOFF window is slightly enlarged, and actually splits into two different regions, one characterized by u – s and d – u pairings and the other with d – u pairs only.
