We present results for thermodynamic observables, gluon and quark propagators in 2-colour QCD at zero temperature and non-zero chemical potential. We find three distinct phase transitions or crossovers as the chemical potential is increased: from a vacuum phase to a superfluid BEC phase, to a confined (quarkyonic) phase characterised by BCS-like scaling, and finally to a deconfined phase. Gluon and quark propagators receive substantial medium modifications as the chemical potential incresases.
