We present the dispersion relations for quasiparticle excitations about the color-flavor locked ground state of QCD at high baryon density. In the presence of condensates which pair light and strange quarks there need not be an energy gap in the quasiparticle spectrum. This raises the possibility of gapless color superconductivity, with a Meissner effect but no minimum excitation energy. Analysis within a toy model suggests that gapless color superconductivity may occur only as a metastable phase.

The paper

Original abstract

We present the dispersion relations for quasiparticle excitations about the color-flavor locked ground state of QCD at high baryon density. In the presence of condensates which pair light and strange quarks there need not be an energy gap in the quasiparticle spectrum. This raises the possibility of gapless color superconductivity, with a Meissner effect but no minimum excitation energy. Analysis within a toy model suggests that gapless color superconductivity may occur only as a metastable phase.

Axial anomaly and magnetism of nuclear and quark matter
hep-ph 2007-10 accept novelty 7.0 of 10

Above roughly 10^19 gauss a stack of neutral-pion domain walls carries more baryon number per unit energy than nuclear matter, and analogous eta or eta-prime walls form in color-superconducting quark matter.

Dense three-flavor quark matter forms a color-flavor locked superconductor whose broken symmetries, gapped spectrum, and modified electromagnetism mirror those of confined hadronic matter.

Crystalline color superconductors

Crystalline color superconducting quark matter can be energetically favored over homogeneous phases in compact-star cores and is chromomagnetically stable, with a shear modulus 20 to 1000 times that of the neutron-star crust.
