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.
