: “Going with the Flow: A Solution to your Sign Problems”
: I will discuss a new solution the sign problem which prevents ab-initio, Monte-Carlo computations regarding many body systems as well as dynamical quantities such as transport coefficients. The solution is based on deforming the domain of the path integral integral into a complex manifold where the sign problem can be mitigated substantially. I will discuss the conceptual and the computational aspects of this idea and give examples of interacting quantum field theories (bosonic and fermionic) at finite density as well as real time dynamics where this method successfully solves the sign problem.
