In physics, a nonlinear X-wave (NLX) is a wave that can travel without distortion. At variance with X-waves, a nonlinear X-wave does exist in the presence of nonlinearity, and in many cases it self-generates from a Gaussian (in any direction) wave packet. The distinctive feature of an NLX is its "biconical" shape, (see figure) which appears as an "X" in any section plane containing the wave peak and the direction of propagation.

dbo:abstract
  • In physics, a nonlinear X-wave (NLX) is a wave that can travel without distortion. At variance with X-waves, a nonlinear X-wave does exist in the presence of nonlinearity, and in many cases it self-generates from a Gaussian (in any direction) wave packet. The distinctive feature of an NLX is its "biconical" shape, (see figure) which appears as an "X" in any section plane containing the wave peak and the direction of propagation. So far, nonlinear X-waves have been only observed in nonlinear optics experiments, and have been predicted to occur in a variety of nonlinear media including Bose–Einstein condensates. (en)
  • Нелинейные икс-волны (англ. Nonlinear X-waves, НЛИВ) — пространственная волна, способная распространяться без искажений. Вариант для случая нелинейности. Обычно представляют собой волновой пакет, характеризуемый распределением Гаусса по всем своим координатам Отличительная особенность НЛИВ — двойной конус в виде креста («Х») в любой из проекций, содержащий максимум волновой функции и направление распространения. Наблюдались только в экспериментах в области нелинейной оптики. Теоретически предсказаны для Конденсата Бозе — Эйнштейна. (ru)
