报告摘要
The creation and manipulation of nonlinear localized waves including various types of solitons are among the paramount and advanced research field in nonlinear physics that generally includes three interdisciplinary directions: chaos, solitons and fractals. Particularly, instead of launching the critical collapses in two dimensional self-focusing systems and 3D supercritical one, novel linear periodic structures in the forms of moiré optical/photonic lattices and nanoscale lattices are nowadays widely introduced to the stabilization of various structures of localized waves like fundamental solitons, gap solitons and vortices, etc. Competing nonlinearity and the combination of quantum optics and nonlinear effects (leading to the formation of quantum nonlinear optics) have also recently been introduced to create robust nonlinear localized waves. This talk would deliver the recent progresses of localized waves made by his group and beyond.
