Chromomagnetic stability of the three flavor   Larkin-Ovchinnikov-Fulde-Ferrell phase of QCD
  We compute in the Ginzburg-Landau approximation the gluon Meissner masses for the Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) phase of QCD with three flavors in the kinematical range where it is energetically favored. We find real Meissner masses and therefore chromomagnetic stability.
