• Based on the renormalization group arguments of the vector manifestation of Harada-Yamawaki hidden local symmetry theory, we obtain a surprisingly simple description of kaon condensation by fluctuating around the "vector manifestation (VM)" fixed point identified to be the chiral restoration point. Our development establishes that the critical density for strangeness condensation is lower than the chiral symmetry restoration density. This result depends only on the renoramlization-group (RG) behavior of the vector interactions. Other effects involved in fluctuating about the bare vacuum are "irrelevant" in the RG about the fixed point. Our results have major effects on the collapse of neutron stars into black holes.
