Abstract
We compute gluon and quark propagators in 2-colour QCD at large baryon chemical potential mu. The gluon propagator is found to be antiscreened in the superfluid, confined phase and screened in the large-mu, deconfined phase. We present the first attempt to determine corresponding electric and magnetic gluon masses. The quark propagator undergoes dramatic modifications in the superfluid region as a result of the formation of a superfluid gap. These modifications include the appearance of zero crossings in the vector part of the (normal) quark propagator, a large suppression of the scalar part, and the emergence of anomalous propagation.
