摘要：

The equation of state of the kaon-condensed phase is studied within a relativistic formalism. We find a self-suppression mechanism such that the kaon condensate decreases the nucleon effective mass through the relativistic effect, which reduces the interaction energy between the nucleon and kaon in a high density region, suppressing the development of the condensate. To get more insight into this feature we extend a chiral symmetry approach and incorporate the relativistic mean field theory. In this extended treatment the sigma mean-field enhances the self-suppression mechanism. Some features of kaon-condensed neutron stars are briefly discussed.
