摘要：

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, to our knowledge, the first observation of asymmetric frequency sidebands of atomic matter waves.
