We consider a generalized Thirring model in 0+1 dimensions at finite density.In order to deal with the resulting sign problem we employ stochasticquantization, i.e., a complex Langevin evolution. We investigate theconvergence properties of this approach and check in which parameter regionscomplex Langevin evolutions are applicable in this setting. To this end wederive numerous analytical results and compare directly with numerical results.In addition we employ indirect indicators to check for correctness. Finally weinterpret and discuss our findings.
