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.
