Title:
Quantum stress within hadrons

Abstract:
The hadronic energy-momentum tensor emerges as a vital 
tool to unravel the energy and stress distributions 
inside hadrons, and provides insights into the nature of 
the strong force. These quantities also play a key role 
in the current and forthcoming experiments with electron-ion 
collisions. Notably, the stress density poses a unique 
challenge due to its dynamical nature within strongly 
coupled systems. In this talk, I will explore the physical 
interpretation of the hadronic energy-momentum tensor and 
the associated gravitational form factors. Emphasis is 
placed on recent advancements in our comprehension of 
hadronic stress through a microscopic lens, utilizing a 
non-perturbative wave function representation. In particular, 
I will show that a consistent treatment of the hadronic 
matrix elements and the Hamiltonian dynamics, including 
a consistent renormalization, is the key to extract the 
quantum stress. Illustrating this approach, I will showcase 
two concrete examples. The first delves into the extraction 
of quantum stress for the pion within holographic light-front 
QCD, while the second focuses on the dissection of quarkonium 
in basis light-front quantization.
