Gauge confinement#

A simplified, illustrative 1+1D toy model of quark confinement: a field squeezed into a fixed-cross-section “flux tube” between two opposite charges, reproducing the linearly growing confinement energy that Kenneth Wilson’s 1974 lattice gauge theory predicted – not a lattice-QCD or first-principles gauge-theory calculation.
