标题： QCD Kondo effect for single heavy quark in chiral-symmetry broken phase

摘要： 我们考虑夸克物质中单个重夸克的量子色动力学（QCD）Kondo效应，该夸克物质由具有手征对称性破缺的轻夸克组成。 在QCD Kondo凝聚中引入几种旋量结构，即粒子投影凝聚、反粒子投影凝聚以及无投影的正常凝聚，我们在路径积分形式下的平均场近似中计算了重夸克获得的吸引力能。 我们表明，当轻夸克具有非零质量时，在低密度下正常凝聚占优，而在高密度下粒子投影凝聚占优。 我们通过Kondo共振来解释这两种凝聚之间的密度依赖性转变。 显示英文摘要

摘要： We consider the quantum chromodynamics (QCD) Kondo effect for a single heavy quark in quark matter composed of light quarks with chiral symmetry breaking. Introducing several spinor structures in QCD Kondo condensates, i.e., particle-projected condensate, antiparticle-projected condensate, and normal condensate without projection, we calculate the attractive energy gained by the heavy quark within the mean-field approximation in the path-integral formalism. We show that the normal condensate is favored at low density and the particle-projected condensate is favored at high density, when the light quark has a nonzero mass. We interpret such a density-dependent transition between the two condensates in terms of the Kondo resonances.
