摘要：

During the seminar, I will provide a brief introduction to the propagation of high-intensity, ultra-narrow and ultra-short light pulses in nonlinear media, a complex multidimensional phenomenon which leads to substantial spatiotemporal optical pulse rearrangement. This problem has attracted strong interest over the past decades, leading to the generation and the manipulation of high-intensity femtosecond and attosecond pulses. Then, I will show our recent contributions to the field of nondiffractive and nondispersive spatiotemporal solitons in Kerr media. We analytically predict the existence of a novel family of spatiotemporal dark solitary wave solutions of the (2+1)D nonlinear Schrödinger equation. We analytically derive the dark solitary waves from hydrodynamic exact soliton solutions of the (2+1)D shallow water Kadomtsev-Petviashvili model, inheriting their complex interaction properties. This opens a novel path for the excitation and control of optical spatiotemporal waveforms of hydrodynamic footprint and multidimensional optical extreme wave phenomena.
