Real-time confinement following a quantum quench to a non-integrable model

Confinement plays an important role in many-body physics from high energy to condensed matter. New results show that it strongly affects the non-equilibrium dynamics after a quantum quench with possible implications from ultracold atoms to QCD. Quarks cannot be observed as free particles in nature because they are confined into baryons and mesons, as a result of the fact that the strong interaction between them increases with their separation....
