  Cold dense quark matter is in a crystalline color superconducting phase
wherever pairing occurs between species of quarks with chemical potentials
whose difference \delta\mu 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 by about a factor of ten at accessible
densities and by much larger factors at higher density. This striking
enhancement reflects the increasingly (1+1)-dimensional nature of the physics
at weaker and weaker coupling. Our results indicate that crystalline color
superconductivity is a generic feature of the phase diagram of cold dense quark
matter, occurring wherever one finds quark matter which is not in the
color-flavor locked phase. If it occurs within the cores of compact stars, a
crystalline color superconducting region may provide a new locus for glitch
phenomena.
