    "abstract": "The nonlinear interaction, due to quantum electrodynamical (QED) effects,\nbetween photons is investigated using a wave-kinetic description. Starting from\na coherent wave description, we use the Wigner transform technique to obtain a\nset of wave-kinetic equations, the so called Wigner-Moyal equations. These\nequations are coupled to a background radiation fluid, whose dynamics is\ndetermined by an acoustic wave equation. In the slowly varying acoustic limit,\nwe analyse the resulting system of kinetic equations, and show that they\ndescribe instabilities, as well as Landau-like damping. The instabilities may\nlead to break-up and focusing of ultra-high intensity multi-beam systems, which\nin conjunction with the damping may result in stationary strong field\nstructures. The results could be of relevance for the next generation of\nlaser-plasma systems.",
