D63 (2001) 074016 | | Subject: | High Energy Physics - Phenomenology; Superconductivity | hep-ph astro-ph cond-mat.supr-con nucl-th | | Affiliation: | MIT), Jeffrey Bowers (MIT), Krishna Rajagopal (MIT | | Abstract: | In any context in which color superconductivity arises in nature, it is likely to involve pairing between species of quarks with differing chemical potentials. For suitable values of the differences between chemical potentials, Cooper pairs with nonzero total momentum are favored, as was first realized by Larkin, Ovchinnikov, Fulde and Ferrell (LOFF). Condensates of this sort spontaneously break translational and rotational invariance, leading to gaps which vary periodically in a crystalline pattern. Unlike the original LOFF state, these crystalline quark matter condensates include both spin zero and spin one Cooper pairs. We explore the range of parameters for which crystalline color superconductivity arises in the QCD phase diagram. If in some shell within the quark matter core of a neutron star (or within a strange quark star) the quark number densities are such that crystalline color superconductivity arises, rotational vortices may be pinned in this shell, making it a locus for glitch phenomena. | | Source: | arXiv, hep-ph/0008208 | | Services: | Forum | Review | PDF | Favorites | |
