Anisotropic two-dimensional RF-dressed potentials for ultracold atoms

Abstract

In this work, the RF-dressed potentials generated using a static magnetic field of a quadrupole trap and various radio frequency (RF) fields, have been theoretically investigated for trapping and manipulations of cold atoms in a two-dimensional (2D) geometry. It is shown that, in this scheme, the RF fields of some particular polarizations and phases can give rise to some novel static and time-dependent anisotropic two-dimensional potentials which are useful to trap and manipulate the cold atoms in the 2D geometry. The generated time-dependent 2D potentials, rotating on the circular ring, can be used for the controlled rotation and oscillation of the cold atom cloud on the circular ring path. The ultracold atoms trapped in these potentials may be used to investigate the interesting physics phenomena such as tunnelling and super-fluidity.
