TL;DR: In this article, the authors present the landmarks of the 10-odd-year progress in this field, focusing on the theoretical modeling of the propagation equations, whose physical ingredients are discussed from numerical simulations.

TL;DR: The filamentation of femtosecond light pulses in air is numerically and experimentally investigated for beam powers reaching several TW and evolution of the filament patterns can be qualitatively reproduced by an averaged-in-time (2D+1)-dimensional model derived from the propagation equations for ultrashort pulses.

TL;DR: It is demonstrated that two-dimensional solitons in media with spatially nonlocal nonlinear response systems, which include thermal nonlinearity and dipolar Bose-Einstein condensates, may support a variety of stationary localized structures, including rotating dipolesolitons.

TL;DR: In this article, a combined theoretical and experimental study of spatiotemporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses is presented.

TL;DR: The experiments and numerical simulations reveal a characteristic spectrotemporal structure of the self-compressed pulses, consisting of a compressible blue wing and an incompressible red pedestal, and explain the underlying mechanism that leads to this structure and examine the scalability of filamentSelf-compression with respect to pulse energy and gas pressure.
