Lattice quantum field theory

Lattice quantum field theory is a computational approach used to study fundamental particles and forces by discretizing space and time into a grid, or lattice. This allows complex quantum interactions, like those in the strong nuclear force, to be simulated numerically. By replacing continuous space with a finite set of points, scientists can perform calculations that are otherwise impossible analytically. It helps to understand behaviors like quark confinement and hadron properties, providing insights into the fundamental structure of matter using powerful computers, bridging theoretical physics and observable phenomena.
