Spatio-temporal vortices: properties, generation and recording

This study develops the theory of the so-called entangled spatio-temporal structures, drawing an analogy with the spatial vortices. Both the methods of their creation and analysis in spatio-time domain are described. In addition, the features of spatio-temporal vortices nested in solitons, and parametric interplay of such spatio-temporal structures are discussed. Finally, the theory of entangled spatio-temporal structures is also extended to other localized fields.
