Query: Line of Dirac monopoles embedded in a Bose-Einstein condensate   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.
