Abstract

The momentum changes caused by localization are a central feature of wave‐particle duality. Investigating these changes in more detail, we find that single‐slit diffraction relies on a form of `interaction‐free' scattering, and that an ideal which‐way measurement can be made without any back‐reaction on the detector. We also consider Kim and Shih's recent realization of Popper's experiment, involving diffraction of entangled particles, and offer an explanation for the results.

The asymmetric effect on mode localization of a symmetric structure possessing nearly equal frequencies is analyzed. A reduction solution for nearly equal frequency perturbation is used to relate modes of a perturbed (asymmetric) structure and modes of original (symmetric) structure. A simple criter
