    "abstract": "Cold, asymptotically dense three-flavor quark matter is in the color-flavor\nlocked (CFL) phase, in which all quarks pair in a particularly symmetric\nfashion. At smaller densities, taking into account a nonzero strange quark mass\nand electric and color neutrality, the CFL phase requires pairing of quarks\nwith mismatched Fermi momenta. We present a classification of all other\npossible, less symmetric, pairing patterns and prove that none of them can\navoid this mismatch. This result suggests unconventional, e.g., spatially\ninhomogeneous, superconducting phases for moderate densities.",
