A radio frequency (RF) transition is used to convert a pure F=2,mF=2 87Rb Bose-Einstein condensate confined in a TOP trap to a mixture of F=2,mF=2 and F=2,mF=1 states. We show that the nature of this coupling process is strongly influenced…
We study a spinor condensate of Rb-87 atoms in F = 1 hyperfine state confined in an optical dipole trap. Putting initially all atoms in mF = 1 component we observe a significant transfer of atoms to other, initially empty Zeeman states…
We consider a spin-orbit coupled system of particles in an external trap that is represented by a deformed harmonic oscillator potential. The spin-orbit interaction is a Rashba interaction that does not commute with the trapping potential…
