Complex Langevin dynamics in the SU(3) spin model at nonzero chemical potential revisited

A bstract The three-dimensional SU(3) spin model is an effective Polyakov loop model for QCD at nonzero temperature and density. It suffers from a sign problem at nonzero chemical potential. We revisit this model using complex Langevin dynamics and assess in particular the justification of this appr...
