Stable self-trapped vortex annuli (VAs) with large values of topological charge S (giant VAs) are not only a subject of fundamental interest, but are also sought for various applications, such as quantum information processing and storage. However, in conventional atomic Bose-Einstein condensates (BECs) VAs with S>1 are unstable. Here, we demonstrate that robust self-trapped fundamental solitons (with S=0) and bright VAs (with the stability checked up to S=5), can be created in the free space…

Frontiers in multidimensional self-trapping of nonlinear fields and matter

Abstract2D and 3D solitons and related states, such as quantum droplets, can appear in optical systems, atomic Bose–Einstein condensates (BECs) and liquid crystals, among other physical settings.

Dipolar bright solitons and solitary vortices in a radial lattice

Stabilizing vortex solitons with high values of the topological charge, S, is a challenging issue in optics, studies of Bose-Einstein condensates (BECs) and other fields. To develop a new approach to

Two-dimensional composite solitons in Bose-Einstein condensates with spatially confined spin-orbit coupling

Semidiscrete Quantum Droplets and Vortices.

The results provide the first realization of stable semidiscrete vortex QDs, including ones with multiple vorticity, and increase the number of sites in fundamental QDs and eventually replace vortex modes by fundamental or dipole ones.

Tail-free self-accelerating solitons and vortices

Self-accelerating waves in conservative systems, which usually feature slowly decaying tails, such as Airy waves, have drawn great interest in studies of quantum and classical wave dynamics. They

Two-dimensional vortex quantum droplets

It was recently found that the Lee-Huang-Yang (LHY) correction to the mean-field Hamiltonian suppresses the collapse and creates stable localized modes (two-component "quantum droplets", QDs) in two

Three-dimensional droplets of swirling superfluids

A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of



Vortices in Bose-Einstein Condensates: Theory

Vortices are pervasive in nature, representing the breakdown of laminar fluid flow and hence playing a key role in turbulence. The fluid rotation associated with a vortex can be parameterized by the
