We propose a novel gravito-optical dipole trap for cold, alkali atoms composed of a blue-detuned, pyramidal-hollow beam propagating upward and the gravity field. When cold atoms from a magneto-optical trap are loaded into the pyramidal-hollow beam (PHB) and bounce inside the PHB, they experience efficient PHB-induced Sisyphus cooling (i.e., intensity-gradient cooling) and repumping-beam-induced geometric...
We propose a novel ac electro-magnetic wave guide for cold neutral atoms in an Ioffe tube, which is based on the interaction of a magnetic dipole moment of a guided 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 guided atoms in the magnetic guiding tube are calculated...
