A Quantitative Framework of Nonperturbative QCD from Topological Vacuum with Application to Parton Structures
Wei-Yang Liu
This dissertation develops a quantitative framework that provides a physical picture for non-perturbative QCD based on the topological structure of the QCD vacuum. By integrating o…
Generic framework for non-perturbative QCD in light hadrons
Wei-Yang Liu
In this paper, we review several topological aspects of the QCD vacuum and recent progress on this quantitative unifying framework for the low-lying hadron physics rooted in QCD by…
The color force acting on a quark in the pion and nucleon
Wei-Yang Liu, Edward Shuryak, Ismail Zahed
In the Operator Product Expansion (OPE) of hard scattering amplitudes, the twist-3 operators describe local colored Lorentz forces acting on a quark, thereby providing a measure of…
Dissipative Quantum Dynamics in Static Network with Different Topologies
Wei-Yang Liu, Hsuan-Wei Lee
We investigate the dissipative dynamics of quantum population and coherence among different network topologies of a quantum network using a quantum spin model coupled to a thermal…
Nucleon electric dipole form factor in QCD vacuum
Wei-Yang Liu, Ismail Zahed
In the QCD vacuum, the nucleon form factors receive contributions from the underlying ensemble of topological pseudoparticles, which are sensitive to a finite vacuum angle . We…
Tomography of the Rho meson in the QCD Instanton Vacuum: Transverse Momentum Dependent Parton Distribution Functions
Wei-Yang Liu, Ismail Zahed
We analyse the rho meson unpolarized and polarized transverse momentum dependent parton distribution functions (TMDPDFs) in the instanton liquid model (ILM). The corresponding TMDs…
