Query: Mixed Kaon Condensation in CFL Matter   Previous work on high-density QCD suggests that the ground state
configuration in the presence of a non-zero neutrino chemical potential
consists of CFL matter plus a homogenous condensate of neutral and positive
kaons. We consider here the stability of this homogenous configuration toward
the production of a charge-separated mixed phase, and find that the system is
indeed stable against the production of such a heterogenous configuration. We
identify the critical value of the fine structure constant which would allow
for phase separation. We also derive dispersion relations for the low-lying
excitations above the kaon-condensed ground state and discuss their possible
phenomenological implications.
