A new model on wave–par ticle duality\nby Donald C. Chang (HKUST) as part of QM Foundations & Nature of Time seminar\n\n\nAbstract\nA well-known mystery in quantum mech anics is wave–particle duality: Is an electron a point mass or a physica l wave? What is the physical meaning of its wave function? About a hundred years ago\, there was a famous debate between Bohr and Einstein on this t opic. Their question is still open today. This talk reviews a new theoreti cal framework to address this problem. We hypothesize that both photons an d electrons are quantized excitation waves of the vacuum\, the physical pr operties of which can be modeled based on the Maxwell theory. Using the me thod of Helmholtz decomposition\, one can show that the wave function of t he particle is associated with an electric vector potential called “ Z ”\, which plays the role of basic field for the excitation wave. Using t his framework\, the quantum wave equations can be derived based on a quant ization of the Maxwell theory. This work suggests that\, the quantum wave function truly represents a physical wave\; the wave packet looks like a “particle” only in the macroscopic view. Because the vacuum excitation obeys the principle of all-or-none\, the probability of detecting this “particle” is related to the wave function as suggested in the Copenha gen interpretation\n LOCATION:https://researchseminars.org/talk/QMFNoT/28/ END:VEVENT END:VCALENDAR
