Anisotropic Instabilities in Trapped Spinor Bose-Einstein Condensates
arXiv:0807.1280 · doi:10.1103/PhysRevA.78.033609
Abstract
We theoretically investigate the effect of an anisotropic trap on the instability of the polar $(m_F=0)$ phase of a spin-1 Bose-Einstein condensate. By considering rigorously the spatial quantization, we show that the growth of the nascent ferromagnetic phase at short times becomes anisotropic with stronger oscillations in the magnetization correlation function along the unconfined direction.
