The Interference Of Electrons

Gong Xiao-guang

This article studies the phenomenon of electronic double slot interference theoretically with the light interference theory and the uncertainty principle and elaborates the interference mechanism of the electronic double slot interference phenomenon to explain that the formation of the electronic double slot interference pattern is not the result produced by the two electronics' action rather than the collective performance of the micro particles and their individual characters.This study provides the explanation of the formation of the electronic double slot interference pattern which differs from that in the textbook.

Interference is a universal consequence of superposition, yet in composite quantum systems it can encode correlations between subsystems. We show that in coupled electron-nuclear dynamics, interference in the nuclear density can arise dynamically even when it is initially absent. Starting from a superposition of orthogonal Born-Oppenheimer electronic states, we demonstrate within the exact factorisation framework that genuine non-adiabatic electron-nuclear correlations induce de-orthogonalisation of the electronic factors, thereby generating interference terms in the nuclear density. Such interference has no counterpart in adiabatic evolution. Unlike conventional nuclear wave-packet interference or interference that merely reflects electronic coherence in a chosen basis, the effect identified here is a manifestation of the compositeness of the full electron-nuclear state. Nuclear density interference thus emerges as a direct dynamical signature of correlated quantum motion in composite systems.

I propose an idealized electron interference experiment with a light-port/dark-port configuration and consider the possible outcomes for the average energy of electric potential that is present in a statistically relevant set of single electron measurements. The changes in energy of electric potential of the electron during its evolution will cause a shift in the kinetic energy or momentum of the electron, and this calculated shift may be interpreted differently for the case of interference and non-interference. I also propose an idealized single electron spatial interference effect and the associated changes in states of electric potential.
