Abstract
Atoms are diffracted at tailored time–modulated complex potential gratings made of light. Modulating both real and imaginary parts separately, the potential winds like a corkscrew in complex space. This temporal helicity induces energy transfers only in one single direction. As a result we present the first observation of asymmetric frequency sidebands of atomic matter waves.Keywords
