Tackling the Sign Problem
arXiv:hep-lat/9311073 · doi:10.1142/S0129183194000313
Abstract
To tackle the sign problem in the simulations of systems having indefinite or complex-valued measures, we propose a new approach which yields statistical errors smaller than the crude Monte Carlo using absolute values of the original measures. The 1D complex-coupling Ising model is employed as an illustration.
