Leveraging neural control variates for enhanced precision in lattice field theory
Paulo F. Bedaque, Hyunwoo Oh
Results obtained with stochastic methods have an inherent uncertainty due to the finite number of samples that can be achieved in practice. In lattice QCD this problem is particula…

A solution for infinite variance problem of fermionic observables
Hyunwoo Oh, Andrei Alexandru, Paulo F. Bedaque +1
Fermionic Monte Carlo calculations with continuous auxiliary fields often encounter infinite variance problem from fermionic observables. This issue renders the estimation of obser…
