We show how to create a novel two-dimensional trap for ultracold atoms from
a conventional magnetic trap. We achieve this by utilizing rf-induced adia
batic potentials to enhance the trapping potential in one direction. We dem
onstrate the loading process and discuss the experimental conditions under
which it might be possible to prepare a 2D Bose condensate. A scheme for th
e preparation of coherent matter-wave bubbles is also discussed.
