Of great physical and mathematical interest is settling the Final State Conjecture concerning the large-time behavior of excited electrons in a non-equilibrium plasma. The non-neutrality of a plasma gives rise to self-consistent electromagnetic fields, which, in turn, drive the particles. The conjecture concerns the relaxation of the fields and the formation of nontrivial coherent structures at large times. This reveals the extremely rich underlying physics, including phase mixing, Landau damping, plasma oscillations, plasma echoes, and resonances. This talk aims to overview recent advances in resolving this conjecture.
