A damped point-vortex model for polar-core spin vortices in a ferromagnetic spin-1 Bose-Einstein condensate
Lewis A. Williamson, P. B. Blakie
Ferromagnetic spin-1 Bose-Einstein condensates in the broken-axisymmetric phase support polar-core spin vortices (PCVs), which are intimately linked to the nonequilibrium dynamics…

Optical response of atom chains beyond the limit of low light intensity: The validity of the linear classical oscillator model
L. A. Williamson, J. Ruostekoski
Atoms subject to weak coherent incident light can be treated as coupled classical linear oscillators, supporting subradiant and superradiant collective excitation eigenmodes. We id…

Anomalous phase ordering of a quenched ferromagnetic superfluid
L. A. Williamson, P. B. Blakie
Coarsening dynamics, the canonical theory of phase ordering following a quench across a symmetry breaking phase transition, is thought to be driven by the annihilation of topologic…
