    Neural Autoregressive Control Variates for the Quantum Monte Carlo Sign Problem

    Bei Qiao, Lei Wang

    cond-mat.str-el · cs.LG · physics.comp-ph

    We train a pair of autoregressive models to construct zero-mean control variates to mitigate the sign problem in quantum Monte Carlo simulations. The two autoregressive networks are confined to the positive- and negative-sign sectors with strictly disjoint support, and each is exactly normalized over its sector. Their difference is therefore structurally zero-mean, providing an unbiased auxiliary observable whose correlation with the sign...
