Creation and revival of ring dark solitons in a toroidal Bose-Einstein condensate

TL;DR

This paper presents a method to create and study the dynamics of multiple ring dark solitons in a toroidal Bose-Einstein condensate, revealing their decay into vortex structures and transition to quantum turbulence.

Contribution

It introduces a protocol for controlled creation of multiple concentric ring dark solitons and analyzes their decay and revival dynamics in a toroidal BEC.

Findings

Ring dark solitons can be created simultaneously in a toroidal BEC.

Decayed solitons form vortex-antivortex necklaces.

Soliton revivals lead to quantum turbulence.

Abstract

We propose a protocol for the simultaneous controlled creation of multiple concentric ring dark solitons in a toroidally trapped Bose-Einstein condensate. The decay of these solitons into a vortex-antivortex necklace shows revivals of the soliton structure, but eventually becomes an example of quantum turbulence.
