Interference of the evolutions of Rb and Na Bose-Einstein condensates
Ma Luo, Chengguang Bao, Zhibing Li
Spin evolution of a mixture of two species of spin-1 Bose-Einstein condensates (Rb and Na) has been investigated beyond the mean field theory. Both analytical expression and numeri…
Effect of magnetic fields on the spin evolution of non-polarized 87Rb Bose-Einstein condensates
Zhifeng Chen, Chengguang Bao, Zhibing Li
The spin mixing dynamics of spin-1 Bose-Einstein condensates with zero magnetization and under an external magnetic field is investigated. The time-dependent solutions are obtained…
Density oscillation in highly flattened quantum elliptic rings and tunable strong dipole radiation
Shuping Situ, Yanzhang He, Chengguang Bao
A narrow elliptic ring containing an electron threaded by a magnetic field B is studied. When the ring is highly flattened, the increase of B would lead to a big energy gap between…
Explanation of the Stern-Gerlach splitting of spinor condensates based on symmetry
Zhibing Li, Chengguang Bao
The Stern-Gerlach splitting of spinor condensates is explained based on the total spin-states with specified SU(2) and permutation symmetries.
