Abstract
En 中文
A briefly formulated update of the recently published review [B.A. Malomed,Multidimensional soliton systems. Adv. Phys. 9(1) (2024), pp. 2301592] on the topic of multidimensional solitons (chiefly, in nonlinear optics and atomic Bose–Einstein condensates (BECs)) is presented. The update briefly summarizes some notable results on this topic that have been reported very recently, and offers a compact outline of the directions of the current experiment and theoretical work in this and related fields. In particular, as concerns newest experimental findings, included are the creation of multiplequantum dropletsin prolate BEC, and the observation of expanding toroidal light structures in linear optics. The update of theoretical results includes the analysis of 2D solitons in the optical system with the quadratic nonlinearity andfractional diffraction, and the prediction of stable 3Dvortex solitonsin various BEC schemes with long-range interactions.
