    They snapped some light onto some iron crystals and had a beer fueled lunch I hope.

    "" despite the substantial volume of research concerning the optical activation of any coherent collective excitation (phonons, magnons, plasmons, and polaritons) in solids, neither a modification of the spectrum ... nor a coupling be-
    tween high-momentum and gamma-point modes at fundamental timescales has been reported. """
