Testing new strategies in finite density
  A new approach for non zero chemical potential simulations is tested in the Gross-Neveu model for infinite flavor number, where the critical line is reconstructed in a large $\mu/T$ interval. A comparison with results from standard imaginary chemical potential approach as well as first results for $N_f=4$ QCD are presented.
