Thickness of the strangelet-crystal crust of a strange star
Mark G. Alford, David A. Eby
It has recently been pointed out that if the surface tension of quark matter is low enough, the surface of a strange star will be a crust consisting of a crystal of charged strange…
Bulk viscosity in kaon-condensed color-flavor locked quark matter
Mark G. Alford, Matt Braby, Andreas Schmitt
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 t…
Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid
Mark G. Alford, Gerald Good
We analyze magnetic flux tubes at zero temperature in a superconductor that is coupled to a superfluid via both density and gradient (``entrainment'') interactions. The example we…
Bulk viscosity in 2SC and CFL quark matter
Mark G. Alford, Andreas Schmitt
The bulk viscosities of two color-superconducting phases, the color-flavor locked (CFL) phase and the 2SC phase, are computed and compared to the result for unpaired quark matter.…
Critical temperature for kaon condensation in color-flavor locked quark matter
Mark G. Alford, Matt Braby, Andreas Schmitt
We study the behavior of Goldstone bosons in color-flavor-locked (CFL) quark matter at nonzero temperature. Chiral symmetry breaking in this phase of cold and dense matter gives ri…
Bulk viscosity due to kaons in color-flavor-locked quark matter
Mark G. Alford, Matt Braby, Sanjay Reddy +1
We calculate the bulk viscosity of color-superconducting quark matter in the color-flavor-locked (CFL) phase. We assume that the lightest bosons are the superfluid mode H and the k…
