We propose a novel ac electro-magnetic guiding and trapping of cold neutral atoms, which is based on the interaction of a magnetic dipole moment of guided and trapped atom with both an ac quadrupole magnetic field in the transverse direction and a dc-bias magnetic field along the guiding axis. The time-averaged magnetic potential and force for the atoms are calculated. And the results show that the potential is high enough to collect and guide nearly all of the cold atoms from a standard magneto-optical trap with a temperature of ~ 120 μK. - 英文摘要: --
