Abstract
We demonstrate matter-wave self-imaging in a stationary light field in the non-Raman-Nath limit. We show that in a non-instantaneous pulsed standing wave grating significant contributions due to the non-negligible atomic center of mass motion and instantaneous Doppler shift can drastically change the condensate momentum distribution, resulting in periodical collapses and recurrences of condensate diffraction probability as a function of the grating pulsing time. The observed matter-wave self-imaging is fundamentally different from the temperal, matter-wave Talbot effect. It is characterized by an atomic population amplitude interference, in the presence of the light field, that simultaneously minimizes all higher (n > 1) diffraction orders and maximizes the zero-th diffraction component.Citation
