- Abstract: The classic Young's double-slit experiment exhibits first-order interference, producing alternating bright and dark fringes modulated by the diffraction effect of the slits. In contrast, here we demonstrate that its time-reversed configuration produces an ideal, deterministic second-order 'ghost' interference pattern devoid of diffraction and first-order effect, with the size dependent on the dimensions of the `effectively extended light source.' Furthermore, the new system enables a range of effects and phenomena not available in traditional double-slit interference studies, including the formation of programmed and digitized interference fringes and the coincidence of the pattern plane and the source plane. Despite the absence of first-order interference, our proposed experiment does not rely on nonclassical correlations or quantum entanglement. The elimination of diffraction through time-reversal symmetry holds promise for advancing superresolution optical imaging and sensing techniques beyond existing capabilities.

Recent investigation into the phenomena of refraction and reflection at temporal boundaries has attracted considerable scholarly interest.
We have delineated a temporal boundary effect amenable to external control through a specifically tailored driving force.
We then unveil the phenomenon of beam splitting-both in time refraction and reflection induced by perturbing the lattice's hopping parameter over time.
