我们研究了由QCD Kondo效应引起的（轻-轻夸克）手性凝聚和重-轻夸克凝聚之间的相互作用，这种相互作用由具有四点相互作用和平均场近似的有效拉格朗日量描述。我们发现近藤凝析油的出现降低了手性凝析油的临界化学势。在临界化学势附近，可出现两种凝析油共存相。本文还讨论了在有限温度和非零电流光夸克质量下这种相互作用的行为。
We investigate the interplay between the (light-light quark) chiral condensate and heavy-light quark condensate induced by the QCD Kondo effect, which is described by an effective Lagrangian with four-point interactions and the mean-field approximation. We find that the appearance of Kondo condensates decreases the critical chemical potential of the chiral condensate. In the region near the critical chemical potential, a coexistence phase with two kinds of condensates can appear. The behavior of such an interplay at finite temperature and with nonzero current light-quark mass is also discussed.
