  We study the phase diagram of two-color Quantum Chromodynamics at finite
temperature and chemical potential. This is done within an effective low-energy
description in terms of quarks, mesons and diquarks. Quantum, thermal and
density fluctuations are taken into account with the functional renormalisation
group approach. In particular, we establish the phenomenon of pre-condensation,
affecting the location of the phase boundary to Bose-Einstein condensation. We
also discuss the Silver Blaze property in the context of the functional
renormalisation group.
