    "abstract": "Plane waves in Kerr media spontaneously generate paraxial X-waves (i.e.\nnon-dispersive and non-diffractive pulsed beams) that get amplified along\npropagation. This effect can be considered a form of conical emission (i.e.\nspatio-temporal modulational instability), and can be used as a key for the\ninterpretation of the out of axis energy emission in the splitting process of\nfocused pulses in normally dispersive materials. A new class of spatio-temporal\nlocalized wave patterns is identified. X-waves instability, and nonlinear\nX-waves, are also expected in periodical Bose condensed gases.",
