Quantum simulation of quantum field theory in the light-front formulation

M Kreshchuk, WM Kirby, G Goldstein, H Beauchemin… - Physical Review A, 2022 - APS
Quantum chromodynamics (QCD) describes the structure of hadrons such as the proton at a
fundamental level. The precision of calculations in QCD limits the precision of the values of …

Nucleon structure from basis light-front quantization

S Xu, C Mondal, J Lan, X Zhao, Y Li, JP Vary… - Physical Review D, 2021 - APS
We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front
approach in the leading Fock-sector representation. We solve for the mass eigenstates from …

Quarkonium as a relativistic bound state on the light front

Y Li, P Maris, JP Vary - Physical Review D, 2017 - APS
We study charmonium and bottomonium as relativistic bound states in a light-front quantized
Hamiltonian formalism. The effective Hamiltonian is based on light-front holography. We use …

Pion and kaon parton distribution functions from basis light front quantization and QCD evolution

J Lan, C Mondal, S Jia, X Zhao, JP Vary… - Physical Review D, 2020 - APS
We investigate the parton distribution functions (PDFs) of the pion and the kaon by
combining quantum chromodynamics (QCD) evolution with the basis light front quantization …

Quark and gluon spin and orbital angular momentum in the proton

S Xu, C Mondal, X Zhao, Y Li, JP Vary… - Physical Review D, 2023 - APS
We address the proton spin puzzle with a fully relativistic and nonperturbative approach
based on a light-front quantized Hamiltonian with quantum chromodynamics (QCD) input …
