Stochastic methods reduce bias in electronic-structure theory calculations, indicating improved accuracy in computations.

This research aims to understand and control the bias introduced in stochastic electronic-structure methods.
Employed the jackknife-2 estimator to reduce bias in stochastic calculations.
Examined three settings: Markovian master equation, Kohn-Sham density functional theory, and Hubbard-model partition function.
Compared a direct estimator and ΣMTP estimator for Hubbard model bias control.
Jackknife-2 estimator significantly reduces bias, improving accuracy in calculations.
The ΣMTP estimator shows lower error compared to the direct estimator after bias control.
Bias control enhances the reliability of stochastic electronic-structure calculations without extra computational cost.
