Abstract

We study a mechanism to create a vorton or three-dimensional skyrmion in phase-separated two-component BECs with the order parameters Ψ 1 and Ψ 2 of the two condensates. We consider a pair of a domain wall (brane) and an antidomain wall (antibrane) stretched by vortices (strings), where the Ψ 2 component with a vortex winding is sandwiched by two domains of the Ψ 1 component. The vortons appear when the domain wall pair annihilates. Experimentally, this can be realized by preparing the phase separation in the order Ψ 1, Ψ 2, and Ψ 1 components, where the nodal plane of a dark soliton in Ψ 1 component is filled with the Ψ 2 component with vorticity. By selectively removing the filling Ψ 2 component gradually with a resonant laser beam, the collision of the brane and antibrane can be made, creating vortons.
