Collective magnetism in arrays of spinor Bose-Einstein condensates

Abstract

We elucidate dipolar magnetic interaction effects in spinor condensates at a low-background field. In particular, we show that arrays of ferromagnetic spinor Bose-Einstein condensates show a rich phase structure that is strongly influenced by the competition of shape anisotropy and higher-order magnetostatic contributions both depending on the condensate's form. © 2013 IOP Publishing and Deutsche Physikalische Gesellschaft.
