SO(3,2) Structure and Distributions of Two-Component Bose-Einstein Condensates with Lower Excitations

SO（3,2）Structure and Distributions of Two—Component Bose—Einstein Condenstates with Lower Excitations

The eigenstates describing two-component Bose–Einstein condensates (BEC) with weakly excitations have been found, by using the SO(3,2) algebraic mean-field approximation. We show that the two-component modified BEC (see Eq.(26)) possesses uniquely super-Poissonian distribution in a fixed magnetic field along direction. The distribution will be uncertain, if B = 0.
