Аннотация:
We propose a simple `virtual slit' for atoms based on the position- and velocity-dependent optical pumping of atoms into an undetected internal state. We show how this slit can be used as a nanometre scale, high-contrast tool for atom lithography as well as a subrecoil collimator for atomic beams.
