  Landau gauge longitudinal and transverse gluon propagators are studied in
lattice QCD with gauge group $SU(2)$ at varying temperature and quark density.
In particular, it is found that the longitudinal propagator decreases with
increasing quark chemical potential at all temperatures under study, whereas
the transverse propagator increases with increasing quark chemical potential at
$T<200$ MeV and does not depend on it at higher temperatures. The relative
strength of chromoelectric and chromomagnetic interactions is also discussed.
