In general, wave effects with ``massive'' particles are much harder to observe compare to massless photons, since their wavelengths are much shorter. Nevertheless, it is possible, especially now when scientists has mastered the tools to produce ultra-cold atomic samples at nanoKelvin temperatures.

For example, in several experiments, researches used a Bose-Einstein condensate (BEC) -- the atomic equivalent of a laser -- to demonstrate the atomic equivalent of the Young's double slit experiment.
