THE RESEARCH OF TEACHING AND FOUNDATION OF QUANTUM MECHANICS

This paper reviews the partial contents of our two manuscripts displayed on arXiv and the nine published papers in some journals, and offers some new expressions. These contents explore the interpretation or research of some concepts and quantum phenomena in quantum mechanics, including foundational or fundamental issues, which delve into deeper questions beneath the basic principles. In our research, we primarily focus on the absence of interaction, or restore the external field potential energy to the interaction energy and consider the related environment qualitatively. We offer a slightly more accessible explanation for several typical quantum phenomena explained using counterintuitive coherent superposition states, summarizing that the wave nature of a particle, i.e., coherent superposition, originates from the interaction of a particle with the environment. We try to propose adding a new postulate to the fundamental postulates or principles of quantum mechanics, which we call the zeroth postulate: any material particle is not free, meaning that the interaction between a particle with its environment cannot be zero. This provides a possible foundation for understanding the wave nature of microscopic particles in quantum mechanics, specifically the coherent superposition pure states. To put this into practice, we propose a new double-slit experiment, hoping that someone will conduct it and predicting that the experimental results will show interference patterns while also identifying which slit a particle has passed through, thus resolving the which-way dilemma. Additionally, we provide explanations for quantum measurements and conservation laws different from those in general books of quantum mechanics.
