Description

We introduce a light-front Hamiltonian approach to nuclear matter with the quark meson coupling (QMC) model with the Basis Light-Front Quantization (BLFQ). Using a relativistic, non-perturbative framework, at the valence quark level for the nucleon, where scalar and vector mean fields mediate interactions to generate the medium dependence. Our calculations of symmetric nuclear matter, including energy per nucleon, pressure, and compressibility,
show consistency with standard QMC models while providing a more robust relativistic treatment. Moreover, the light-front framework enables boost invariant calculations of in-medium parton distribution functions (PDFs). By linking macroscopic thermodynamic properties with microscopic nucleon substructure, this study offers new insights into the nuclear EMC effect and bridges low-energy nuclear physics with high energy QCD phenomenology.
