Phase diagrams and Thomas-Fermi estimates for spin-orbit coupled
Bose-Einstein Condensates under rotation

Amandine Aftalion, Peter Mason
We provide complete phase diagrams describing the ground state of a trapped spinor BEC under the combined effects of rotation and a Rashba spin orbit coupling. The interplay between the different parameters (magnitude of rotation, strength of the spin orbit coupling and interaction) leads to a rich ground state physics that we classify. We explain some features analytically in the Thomas Fermi approximation, writing the problem in terms of the total density, total phase and spin. In some regions of the phase diagrams, we relate the patterns to a ferromagnetic energy.
