Interplay between chiral symmetry breaking and the QCD Kondo effect

Understand

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.
