Effective theories for cold atom systems with enhanced symmetry
15.06.2011 at 10:00
For spin-1 bosons, the phase diagram around the ferromagnetic SU(3) point is presented and compared to the theoretical predictions. For spin-3/2 fermions in the vicinity of the staggered antiferromagnetic SU(4) point it is shown that the Sp(4) perturbation favors the ordered phase. The effects of further breaking the Sp(4) symmetry down to SU(2) are addressed.
