D-term of nuclei exhibits kinks at magic neutron numbers, showing strong sensitivity of mechanical properties to shell structure.
Relativistic EMT distributions in polarized nucleons recover good and bad light-front components in the IMF after including polarization effects.
In light-front holographic QCD the nucleon gravitational form factor B_N(t) vanishes exactly in the symmetric limit due to an antisymmetric longitudinal factor and remains strongly suppressed for realistic nucleon wave functions, explaining its observed smallness.
A hadronic approach based on dispersion relations and meson dominance achieves a successful description of lattice QCD data for gravitational form factors of pions and nucleons.

Origin of the nucleon gravitational form factor $B_N(t)$: Exposition in light-front holographic QCD
In light-front holographic QCD the nucleon gravitational form factor B_N(t) vanishes exactly in the symmetric limit due to an antisymmetric longitudinal factor and remains strongly suppressed for realistic nucleon wave functions, explaining its observed smallness.
