WHY WAVES? The Schrödinger Equation, Wave-Particle Duality, the Uncertainty Principle, and Quantum Measurement from One Algebra — A Visual Guide from A_F = ℂ ⊕ ℍ ⊕ M₃(ℂ)

Abstract

Abstract: We derive the Schrödinger equation, wave-particle duality, the uncertainty principle, the double slit experiment, and quantum measurement from the ascending superoperator of A_F = ℂ ⊕ ℍ ⊕ M₃(ℂ) at KMS inverse temperature β = 2π. The crystal's four eigenvalues {1, ½, ⅓, ⅙} are the four frequency bands of the vacuum's wavelet decomposition. The MERA tensor network is a discrete wavelet transform (confirmed: Alves 2024, wMERA = MERA + DWT). Wave-particle duality is the Fourier transform between a single MERA layer (particle) and the full tower (wave). The uncertainty principle arises from the finite bond dimension χ = 6. Measurement is the ascending superoperator destroying the kernel (24 mixed modes). The Schrödinger equation is the continuous limit of the MERA circuit, with H = generator of the ascending superoperator and i = Wick rotation from imaginary to real time. The vacuum oscillates at β = 2π (Bisognano-Wichmann theorem); the crystal decomposes this oscillation into four harmonics; those harmonics are the four forces. Nine independent research traditions confirm this synthesis: Feynman, Wilson, Bisognano-Wichmann, Daubechies, Vidal, Swingle, Harlow-Preskill, Evenbly-Vidal, and Alves. Five figures, an interactive 3D HTML demonstration, and a Python verification script are included. Zero free parameters.

Wave-Particle Duality

Reinhold A. Bertlmann, Nicolai Friis

Abstract This chapter examines some crucial experiments and basic principles of quantum mechanics that have strongly influenced the development of quantum theory in its modern form: starting from Planck’s law of black-body radiation and its derivation using the quantization of energy; Einstein’s photon hypothesis for the puzzle presented by the photoelectric effect and its test via the Millikan experiment; the Compton effect; Bohr’s theses for the structure of the hydrogen atom and the complementarity of waves and particles i.e., the wave-particle duality, culminating in de Broglie’s ideas for matter waves and their confirmation in the Davisson-Germer experiment for electron diffraction from a crystal; Heisenberg’s uncertainty principle for position and momentum as well as for energy an time; the famous double-slit experiment and Born’s probability interpretation, and finally the provocative thought experiment of Schrödinger’s cat

Quantum fluctuations and the double-slit experiment

Jaume Giné

The double-slit experiment is a demonstration of wave-particle duality and one of the most fundamental experiments that help us understand the nature of quantum mechanics. In this work, we give a new explanation of this experiment in terms of the uncertainty principle and vacuum fluctuations. This explanation allows one to understand why the electron interferes with itself when being shot through the double-slit.

Schrödinger equation for various quantum systems based on Heisenberg's uncertainty principle

Kexin An

This article establishes the proof of the Schrödinger equation for numerous quantum systems, utilizing Heisenberg's uncertainty principle. The Fourier transform connects functions in the time and frequency domains, resulting in the mathematical inequality that is the foundation of the uncertainty principle. In the part of Methods and Theory, the article derives the uncertainty principle through Fourier transforms by defining the mean and variance of angular frequency and time, and subsequently expanding the integral. This establishes the fundamental connection between time and frequency domains, illustrating the constraints imposed by quantum mechanics. In the part of Results and Application, the article applies the uncertainty principle to derive the Schrödinger equation under different conditions: free particle, particle in a box, harmonic oscillator, and hydrogen atom. For each case, the article assumes wave function solutions, uses the uncertainty in position and momentum to estimate kinetic and potential energies, and shows that the total energy matches the ground state energy derived from the Schrödinger equation. The results highlight the critical role of Heisenberg's uncertainty principle in understanding key aspects of quantum mechanics, providing a unified framework for these diverse systems.
