手征对称性破缺与QCD近藤效应的相互作用
Interplay between chiral symmetry breaking and the QCD Kondo effect
摘要：
在平均场近似下研究了由QCD近藤效应引起的手征凝聚体（轻-轻夸克）和重-轻夸克凝聚体之间的相互作用.我们发现近藤凝聚体的出现降低了手性凝聚体的临界化学势。在临界化学势附近，可以出现两种凝聚体共存的相。本文还讨论了在有限温度和非零流轻夸克质量下这种相互作用的行为。
英文摘要：
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.
