The phenomenon known as “sign problem” plagues many lattice quantum field theories at finite density and consists on the presence of imaginary terms in the action. So far this problem has prevented a complete study of the QCD phase diagram. I work on a new approach for the regularization of lattice field theories on Leschetz thimbles, which has the property of keeping the imaginary part of the action constant, thus enabling the use of Monte Carlo methods to compute expectation value of observables for field theories at finite density. This research topic is challenging both from a theoretical and a computational point of view, as it needs a massive amount of code parallelization.
