Fermion Condensates in Two Colours Finite Density QCD at Strong Coupling
  We study unquenched lattice SU(2) at nonzero chemical potential at strong coupling and with eight flavours of Kogut-Susskind fermions. Introducing a diquark source term we analyze the behaviour of different types of fermion condensates. Using a non standard approach we can obtain results at zero external source without extrapolations. We find strong evidences for a (high density) second order phase transition where a diquark condensate appears. The corresponding critical chemical potential is in good agreement with half the pion mass.
