  Centre sector transitions in QCD-like theories with dynamical quark matter
are investigated. In the hadronic phase, these transitions still take place in
the infinite volume at zero temperature limit despite of the explicit breaking
of the centre symmetry by the matter fields. This finding is supported by
simulations of the SU(2) Yang-Mills theory with Higgs matter. The
phenomenological impact of the centre sector transitions for dense but confined
matter is explained: centre dressed quarks acquire Bose statistics and form a
so-called Fermi-Einstein condensate. This mechanism is further illustrated in
the Schwinger model where it solves the Silver-Blaze problem.
