TL;DR

This paper demonstrates the creation of a line of Dirac monopoles in a Bose-Einstein condensate using laser and magnetic field techniques, revealing vortex structure changes and collective mode transitions.

Contribution

It introduces a novel method to embed a line of Dirac monopoles in a BEC and explores the resulting vortex and collective mode phenomena.

Findings

Vortex structure transforms with more than six monopoles

Collective modes reveal transition dynamics

Monopole line creation using laser and magnetic field techniques

Abstract

The gauge field of a uniform line of magnetic monopoles is created using a single Laguerre-Gauss laser mode and a gradient in the physical magnetic field. We study the effect of these monopoles on a Bose condensed atomic gas, whose vortex structure transforms when more than six monopoles are trapped within the cloud. Finally, we study this transition with the collective modes.
