Normalizing Flows to Reconstruct Pseudo-PDFs
Yamil Cahuana Medrano, Kostas Orginos
We investigate a normalizing-flow approach for reconstructing parton distribution functions (PDFs) from synthetic matrix-element data. Our framework combines Gaussian Process prior…
Lattice QCD and Particle Physics
Andreas S. Kronfeld, Tanmoy Bhattacharya, Thomas Blum +79
Contribution from the USQCD Collaboration to the Proceedings of the US Community Study on the Future of Particle Physics (Snowmass 2021).
Probing for the Trace Estimation of a Permuted Matrix Inverse Corresponding to a Lattice Displacement
Heather Switzer, Andreas Stathopoulos, Eloy Romero +2
In this work, we study probing for the more general problem of computing the trace of a permutation of , say . The motivation comes from Lattice QCD where we need…
Multigrid deflation for Lattice QCD
Eloy Romero, Andreas Stathopoulos, Kostas Orginos
Computing the trace of the inverse of large matrices is typically addressed through statistical methods. Deflating out the lowest eigenvectors or singular vectors of the matrix red…
Simulating the weak death of the neutron in a femtoscale universe with near-Exascale computing
Evan Berkowitz, M. A. Clark, Arjun Gambhir +9
The fundamental particle theory called Quantum Chromodynamics (QCD) dictates everything about protons and neutrons, from their intrinsic properties to interactions that bind them i…
Deflation as a Method of Variance Reduction for Estimating the Trace of a Matrix Inverse
Arjun Singh Gambhir, Andreas Stathopoulos, Kostas Orginos
Many fields require computing the trace of the inverse of a large, sparse matrix. The typical method used for such computations is the Hutchinson method which is a Monte Carlo (MC)…
