A realization of Yangian and its applications to the bi-spin system
Shuo Jin, Kang Xue, Bing-Hao Xie
Yangian is realized in the bi-spin system coupled with a time-dependent external magnetic field. It is shown that generators can describe the transitions betw…

SO(3,2) structure and distributions of two-component Bose-Einstein condensate with lower excitations
Hong-Biao Zhang, Bing-Hao Xie, Mo-Lin Ge
The wave function describing two-component Bose-Einstein condensate with weakly excitations has been found, by using the SO(3,2) algebraic mean-field approximation. We show that th…
