Journal Article

We study interactions between bright matter-wave solitons which acquire chiral transport dynamics due to an optically-induced density-dependent gauge potential. Through numerical simulations, we find that the collision dynamics feature several non-in... Read More about Non-integrable dynamics of matter-wave solitons in a density-dependent gauge theory.

Measuring the disorder of vortex lattices in a Bose-Einstein condensate (2016)
Journal Article
Rakonjac, A., Marchant, A., Billam, T., Helm, J., Yu, M., Gardiner, S., & Cornish, S. (2016). Measuring the disorder of vortex lattices in a Bose-Einstein condensate. Physical Review A, 93(1), Article 013607. https://doi.org/10.1103/physreva.93.013607

We report observations of the formation and subsequent decay of a vortex lattice in a Bose-Einstein condensate confined in a hybrid optical-magnetic trap. Vortices are induced by rotating the anharmonic magnetic potential that provides confinement in... Read More about Measuring the disorder of vortex lattices in a Bose-Einstein condensate.
