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