Color Flavor Locked Quark matter properties
Quark matter at its highest densities; is expected to become a color superconductor and transition to a phase called color flavor locking (CFL)[1]. Because of asymptotic freedom, the theory becomes weaker at high densities [1] and some kind of superconductivity can be expected[2]. At the CFL phase it behaves as a superfluid[3]and has Chiral Symmetry breaking[1]. Possible observations or experim...
متن کاملThe rigidity of three flavor quark matter
Cold three flavor quark matter at large (but not asymptotically large) densities may exist in a crystalline color superconducting phase. These phases are characterized by a gap parameter ∆ that varies periodically in space, forming a crystal structure. A Ginzburg-Landau expansion in ∆ shows that two crystal structures based on cubic symmetry are particularly favorable, and may be the ground sta...
متن کاملInstabilities in two flavor quark matter
I discuss briefly the instabilities of two flavor quark matter, paying attention to the gradient instability which develops in the g2SC phase in the Goldstone U(1)A sector.
متن کاملThe crystallography of three-flavor quark matter
We analyze and compare candidate crystal structures for the crystalline color superconducting phase that may arise in cold, dense but not asymptotically dense, three-flavor quark matter. We determine the gap parameter ∆ and free energy Ω(∆) for many possible crystal structures within a Ginzburg-Landau approximation, evaluating Ω(∆) to order ∆. In contrast to the two-flavor case, we find a posit...
متن کاملNeutrino Rates in Color Flavor Locked Quark Matter
We study the weak interaction rates involving Goldstone bosons in the Color Flavor Locked (CFL) quark matter. Neutrino mean free path and the rate of energy loss due to neutrino emission in a thermal plasma of CFL pions and kaons is calculated. We find in addition to neutrino scattering off thermal mesons, novel Cherenkov like processes wherein mesons are either emitted or absorbed contribute t...
