Description
Summary:The static longitudinal and transverse gluon propagators in the Landau gauge are studied in 2 + 1 lattice QCD with nonzero isospin chemical potential μ I . Parameterization of the momentum dependence of the propagators is provided for all values of the chemical potential under study. We find that the longitudinal propagator is infrared suppressed at nonzero μ I with suppression increasing with increasing μ I . It is found, respectively, that the electric screening mass is increasing with increasing μ I . Additionally, we analyze the difference between two propagators as a function of the momentum and thus compare interactions in chromoelectric and chromomagnetic sectors.
