Shrinking Young's Double-Slit Experiment 10 Million-Fold Reveals Atoms Vibrating in Sync
A University of Tokyo research group has used adjacent atomic columns in a silicon crystal—spaced 136 pm apart—as a natural double slit, publishing in Nature an interferometric measurement that shrinks Young's experiment by a factor of 10 million. By reading the visibility of the interference fringes, the method quantifies the stiffness of atomic bonds and their correlated thermal vibrations, potentially offering atomic-level insight for heat-dissipation design in semiconductors.
