Abstract: (IOP)

Recently, we have introduced a novel approach to deal with the sign problem that prevents the Monte Carlo simulations of a class of quantum field theories (QFTs). The idea is to formulate the QFT on a Lefschetz thimble. Here we review the formulation of our approach and describe the Aurora Monte Carlo algorithm that we are currently testing on a scalar field theory with a sign problem.
