Mass-Induced Crystalline Color Superconductivity
نویسندگان
چکیده
We demonstrate that crystalline color superconductivity may arise as a result of pairing between massless quarks and quarks with nonzero mass ms. Previous analyses of this phase of cold dense quark matter have all utilized a chemical potential difference δμ to favor crystalline color superconductivity over ordinary BCS pairing. In any context in which crystalline color superconductivity occurs in nature, however, it will be ms-induced. The effect of ms is qualitatively different from that of δμ in one crucial respect: ms depresses the value of the BCS gap ∆0 whereas δμ leaves ∆0 unchanged. This effect in the BCS phase must be taken into account before ms-induced and δμ-induced crystalline color superconductivity can sensibly be compared.

Angular Momentum Mixing in Crystalline Color Superconductivity
In crystalline color superconductivity, quark pairs form at non-zero total momentum. This crystalline order potentially enlarges the domain of color superconductivity in cold dense quark matter. We present a perturbative calculation of the parameters governing the crystalline phase and show that this is indeed the case. Nevertheless, the enhancement is modest, and to lowest order is independent...
متن کاملCrystalline Color Superconductivity
We give an introduction crystalline color superconductivity, arguing that it is likely to occur wherever quark matter in which color-flavor locking does not occur is found. We survey the properties of this form of quark matter, and argue that its presence in a compact star may result in pulsar glitches, and thus in observable consequences. However, elucidation of this proposal requires an under...
متن کاملOpening the Crystalline Color Superconductivity Window
Cold dense quark matter is in a crystalline color superconducting phase wherever pairing occurs between species of quarks with chemical potentials whose difference δμ lies within an appropriate window. If the interaction between quarks is modeled as point-like, this window is rather narrow. We show that when the interaction between quarks is modeled as single-gluon exchange, the window widens b...
متن کاملA Diagrammatic Approach to Crystalline Color Superconductivity
We present a derivation of the gap equation for the crystalline color superconducting phase of QCD which begins from a one-loop Schwinger-Dyson equation written using a Nambu-Gorkov propagator modified to describe the spatially varying condensate. Some aspects of previous variational calculations become more straightforward when rephrased beginning from a diagrammatic starting point. This deriv...
متن کاملCritical couplings in Crystalline Color superconductivity
Solving the Schwinger-Dyson equations, we analyze the pairing of quarks in asymmetric quark matter where quarks have different chemical potentials. We show that in the asymmetric quark matter a crystalline color-superconducting gap opens when the quark coupling is stronger than a critical value. The critical coupling is nonzero, since the infrared divergence is lessened when the momenta of pair...
