What Happens Inside a Proton?

The video explores the challenges and techniques in simulating atomic nuclei and quantum systems. It covers the basics of quantum electrodynamics (QED) and density functional theory (DFT), highlighting the complexity of simulating quantum interactions. The focus then shifts to quantum chromodynamics (QCD) and the strong force, explaining why traditional methods struggle with these calculations. Lattice QCD is introduced as a method to simulate quantum fields directly, using techniques like Monte Carlo sampling and Wick rotation. The video concludes with the potential of lattice QCD to enhance our understanding of quantum fields and hadrons.
