摘要
We analyze the variation behavior of chiral quark condensates in vacuum and in strong interacting matter against the parameters in the effective gluon propagators in Dyson-Schwinger equation approach. The obtained results indicate that the quark confinement enhances the quark condensate, and the screening of the confinement suppresses the response of the condensate to the chemical potential.
