主　　题：ultracold atom magnetic levitation dimple trap 

摘      要：We report a detailed study of magnetically levitated loading of ultracold ^(133)Cs atoms in a dimple *** atomic sample was produced in a combined red-detuned optical dipole trap and dimple trap formed by two small waist beams crossing a horizontal *** magnetic levitation for the ^(133)Cs atoms forms an effective potential for a large number of atoms in a high spatial *** of the number of atoms loaded and trapped in the dimple trap on the magnetic field gradient and bias field is in good agreement with the theoretical *** method has been widely used to obtain the Bose–Einstein condensation atoms for many atomic species.
