Crystalline 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 کاملMass-Induced Crystalline Color Superconductivity
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 ...
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 کاملCrystalline Color Superconductivity in Dense Matter
In this talk I will discuss a recently proposed color superconducting phase of asymmetric quark matter where the up and down quark have different chemical potential, being in chemical equilibrium with electrons. Using Schwinger-Dyson equations derived from an effective theory of low-energy quasiparticles, we examine both the case of an effective four Fermi interaction (appropriate for intermedi...
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...
