Multigrid deflation for Lattice QCD

open access: yesJournal of Computational Physics, 2020
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 reduces the variance of the trace estimator. This work summarizes our efforts to reduce the computational cost of computing the deflation space while achieving the desired ...

Heavy-hadron interactions from Lattice QCD

open access: yesEPJ Web of Conferences, 2018
I review recent progress in heavy hadron spectroscopy and from ab-initio Lattice QCD calculations.After motivating lattice calculations for heavy-hadrons by contrasting recent LHCb results charmed and doubly-charmed baryons with lattice predictions ...

Vacuum correlators at short distances from lattice QCD

open access: yesJournal of High Energy Physics, 2021
Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

Small bits of cold dense matter

open access: yesPhysics Letters B, 2018
The behavior of QCD at high baryon density and low temperature is crucial to understanding the properties of neutron stars and gravitational waves emitted during their mergers.

Analytical relation between quark confinement and chiral symmetry breaking in odd-number lattice QCD

open access: yesEPJ Web of Conferences, 2014
To clarify the relation between confinement and chiral symmetry breaking in QCD, we consider a temporally odd-number lattice, with the temporal lattice size Nt being odd.

Master integrals for two-loop QCD corrections to quark quasi PDFs

open access: yesJournal of High Energy Physics, 2020
We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

Chiral Fermions Algorithms In Lattice QCD

open access: yesEast European Journal of Physics, 2019
The theory that explains the strong interactions of the elementary particles, as part of the standard model, it is the so-called Quantum Chromodynamics (QCD) theory.
