在相对论平均场模型下，用密度泛函理论研究了带电K介子凝聚一级相变过程中混合相的非均匀结构。考虑电场效应，适当应用吉布斯条件，数值计算了核子、电子和凝聚态K介子的密度分布。阐明了电荷屏蔽效应的重要性，从而证明了麦克斯韦结构的有效性。研究了表面效应对密度分布的影响。
Non-uniform structures of mixed phases at the first-order phase transition to charged kaon condensation are studied using a density functional theory within the relativistic mean field model. Including electric field effects and applying the Gibbs conditions in a proper way, we numerically determine density profiles of nucleons, electrons and condensed kaons. Importance of charge screening effects is elucidated and thereby we show that the Maxwell construction is effectively justified. Surface effect is also studied to figure out its effect on the density profiles.
