Fermionic Sign Problem Minimization by Constant Path Integral Contour Shifts
Christoph Gäntgen, Evan Berkowitz, Thomas Luu +2
The path integral formulation of quantum mechanical problems including fermions is often affected by a severe numerical sign problem. We show how such a sign problem can be allevia…

Moments of Parton Distributions Functions from Lattice QCD at the Physical Point
Marcel Rodekamp, Michael Engelhardt, Jeremy R. Green +5
We present a Lattice QCD calculation of the second Mellin moments of the nucleon axial, vector and tensor parton distribution functions (PDFs). The calculation is performed at the…
