Abstract
We demonstrate climbing of cold atoms against the gravity in a one-dimensional vertical laser standing wave. At an appropriately chosen laser–atom detuning, we show that freely falling atoms change the direction of motion and move upward. The effect is due to a tiny interplay between internal and external atomic degrees of freedom in a rigid optical lattice.
