    "abstract": "We analyze the free energy of charge and color neutral 2-flavor quark matter\nwithin the BCS approximation. We consider both the homogeneous gapless\nsuperconducting phase and the heterogeneous mixed phase where normal and BCS\nsuperconducting phases coexist. We calculate the surface tension between normal\nand superconducting phases and use it to compare the free energies of the\ngapless and mixed phases. Our calculation, which retains only the leading order\ngradient contribution to the free energy, indicates that the mixed phase is\nenergetically favored over an interesting range of densities of relevance to 2\nflavor quark matter in neutron stars.",
