Bulk viscosity in kaon-condensed color–flavor-locked quark matter
Bulk viscosity in kaon-condensed color–flavor-locked quark matter
Color-flavor locked (CFL) quark matter at high densities is a color superconductor, which spontaneously breaks baryon number and chiral symmetry.Its low-energy thermodynamic and transport properties are therefore dominated by the H (superfluid) boson, and the octet of pseudoscalar pseudo-Goldstone bosons of which the neutral kaon is the lightest.We study the …
