Kaon Condensation and Dynamical Nucleons in Neutron Stars

Abstract
We discuss the nature of the kaon condensation phase transition. We find several remarkable features which, if kaons condense in neutron stars, will surely affect superfluidity and transport properties. The mixed phase region occupying a large fraction of the star is permeated with microscopic drops located at lattice sites of one phase immersed in the background of the other phase. The electric charge in the drops is opposite to that of the background phase and nucleons have a mass approximately a factor of 2 different depending on whether they are in the drops or the background phase.
