Atom trapping in RF-dressed magnetic potentials with, and without, time-averaging

Modification of the adiabatic potential that a cold atom experiences in a magnetic field by applying strong radio-frequency radiation gives many new possibilities. Systems that we have experimentally demonstrated include a two-dimensional Bose gas (where the potential is much smoother than in our previous experiments with sheets of laser light); this potential has a significant anharmonic component in the radial direction that can be useful in experiments on rapidly rotating quantum gases. We have also demonstrated a ring-shaped cloud in a time-averaged adiabatic potential. Progress towards imaging small numbers of atoms will also be discussed including recent work on an accordion lattice where the spacing between the potential wells in an optical lattice is expanded to effectively magnify the system to obtain better resolution. The development of these techniques will allow experiments on direct quantum simulation of strongly correlated many body systems by cold-atom experiments.
