Abstract: | A large variety of trapping and guiding potentials can be designed by bringing cold atoms close to charged or current-carrying
material objects. Using a current-carrying wire we demonstrate how to build guides and traps for neutral atoms and using a
charged wire we study a 1/r
2 singularity. The simplicity and versatility of the principles demonstrated in our experiments will allow for miniaturization
and integration of atom optical elements into matter-wave quantum circuits.
