We present some recent results on inhomogeneous phases and baryons in the 1+1-dimensional Gross-Neveu model at finite temperature and finite chemical potential. It is known, that in the large $N_f$-limit the system shows an inhomogeneous condensate at low temperature and large chemical potential. We address the question whether a breaking of translation invariance is also seen for finite $N_f$, when quantum fluctuations are not suppressed. Results for $N_f=8$ and $N_f=2$ are presented. The simulation results indicate that many qualitative features of the solution for large $N_f$ are rediscovered for finite $N_f$. The talk is based on two recent works in collaroration with L. Panullo and M. Wagner from Frankfurt and with J. Lenz and B. Wellegehausen from Jena.
