Quantum Motion of Atoms in a Magnetic Waveguide

Based on the magnetic atomic guidance model proposed in our previous paper[Opt.Commun.160(1999)72],the quantum motion of atoms in a magnetic tube is discussed in detail.The non-adiabatic loss of atoms as result of spin-flip transition and the adiabatic condition for keeping atoms in the guidable state are also analysed.The result shows that the atoms can be guided in the magnetic waveguide with a higher guiding efficiency by choosing suitable parameters of the magnetic tube.
