Wave-particle Duality of Macroscopic Particles

Authors: Mingshan Ye

Different schools have different explanations for the wave-particle duality of microscopic particles. Hidden variable interpretation, pilot wave interpretation, stochastic processes interpretation and so on all think that the generation of wave-particle duality has deeper reasons. According to these interpretations, macroscopic objects can also exhibit significant wave-particle duality. The authors performed a "round-hole diffraction experiment of powder particles": some powder particles of the same mass and shape are freely dropped to a plane one by one through a circular hole. At first, the powder particles are distributed disorderly on the plate in the box. With the increase of the number of falling powder particles, a diffraction pattern composed of several concentric rings is gradually presented. This implies that wave-particle duality is not unique to microscopic particles, and it is also exhibited by macroscopic objects. The experimental results help to reveal the nature of wave-particle duality.
