9. Waves and Particles

Sarma N. Gullapalli

On the question of wave-particle duality, from the historic Bohr-Einstein debates a century ago, to this day, the view expressed in Niels Bohr’s Complementarity Principle has become well established, confirmed by numerous experiments: If the observation is for wave nature, then the particle changes to wave, and if the observation is for particle nature, then the particle remains particle. However, recently this view has been challenged. With proof based on the definition of wave function, it has been shown that particle always remains particle and its wave function always remains wave, no mysterious change from particle to wave and vice versa.

Entanglement of the wave–particle duality of particles has attracted enormous attention as one of fundamental feature of quantum mechanics. Herein, we systematically studied the wave–particle entanglement of the particle system composed of N particles. The results indicate that the particle system has the wave–particle entanglement after the interaction, when the wave function of any one of the system can be obtained by using same basis vectors before the interaction. Moreover, a construction method of the wave–particle entanglement state is found for the particle system. Finally, the photons can show the wave–particle entanglement in the previous experimental work, which was further confirmed by the construction method. The results provide a new understanding for the entanglement of the wave–particle duality.

In this paper, we demonstrate the significance of Non-Einsteinian view of relativity in relation to wave model of particle and particle model of wave. To accommodate wave-particle dualism, we have considered de-Broglie’s matter wave concept and Compton Effect. The kinematics of the photon and the photon emitter particle (photon-gun) are taken into consideration. Then, we have correlated the motion related parameters of the gun with the characteristics of the photon. This provides a correlation between wave aspect of particle (matter wave) and particle aspect of wave.
