Thirring model at finite density in 2+1 dimensions with stochastic quantization

Understand

We consider a generalization of the Thirring model in 2+1 dimensions at finite density.

• We employ stochastic quantization and check for the applicability in the finite density case to circumvent the sign problem.
• To this end we derive analytical results in the heavy dense limit and compare with numerical ones obtained from a complex Langevin evolution.
• Furthermore we make use of indirect indicators to check for incorrect convergence of the underlying complex Langevin evolution.
