Blueshift of an Electron in Amplitude Splitting Interference

Published Jul 1, 2014• 0 citations

Abstract

We consider a single electron amplitude splitting interference experiment with respect to the possibility of a blueshift in energy/momentum due to the changes in static electric potential.

Potential Energy Shift in Single Electron Spatial Interference

Thomas Alexander Meyer

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.

Unlocking the Mystery of Interference Patterns in Electron and Photon Double-Slit Experiments and the Puzzle of ‘Waves Without Medium’

Henok Tadesse

The formidable problem with double-slit experiments is: if electrons and photons exhibit wave properties (seen as interference patterns), then what is waving? What is the medium for transmission of ‘electron waves’? Such a medium has been disproved experimentally, in the case of the photon, and not even conceivable for the electron. Erwin Schrodinger was on the right track with his view of the electron as a ‘smeared’ object, rather than as a point particle. Then how is a wave possible without a medium? How can a wave property and a particle property co-exist in a single physical entity (wave- particle duality)? Nature uses a simple and subtle trick : the average electron mass density at a given region of space is directly proportional to the root mean square (RMS) intensity of oscillation (velocity) of the electron (the electron wave) in that region. The instantaneous mass density of the electron at a given point is directly proportional to the instantaneous magnitude of vibrational velocity of the electron at that point. The average photon energy density in a given region of space is directly proportional to the root mean square of rate of change of the electric and magnetic fields in that region. The instantaneous energy density of the photon at a given point of space and time is directly proportional to the magnitude of rate of change of the electric and magnetic fields at that point. The rate of change of electric and magnetic fields in turn depends on the frequency, amplitude and phase of the wave. The electron mass and photon energy will always be concentrated at regions of high wave amplitude. This means that the electron and the photon are dragged by their respective waves. The new theory provides a hint on the mystery behind Planck’s relation: E=h.f. Higher frequency photons have higher energy than lower frequency photons just because higher frequency photons also have higher amplitudes of electric and magnetic field oscillations. If we assume that ordinary waves also have the same fundamental properties as electron waves, then we may be able to explain the lack of backward propagation in Huygens’ principle. We may be able to explain why the bouncing oil droplet in the Couder-Fort oil bath experiment starts to go in the direction of the wave propagation.

Effects of Hydrostatic Pressure and Electric Field on the Electron-Related Optical Properties in GaAs Multiple Quantum Well

D.A. Ospina, Miguel Eduardo Mora-Ramos, C.A. Duque

The properties of the electronic structure of a finite-barrier semiconductor multiple quantum well are investigated taking into account the effects of the application of a static electric field and hydrostatic pressure. With the information of the allowed quasi-stationary energy states, the coefficients of linear and nonlinear optical absorption and of the relative refractive index change associated to transitions between allowed subbands are calculated with the use of a two-level scheme for the density matrix equation of motion and the rotating wave approximation. It is noticed that the hydrostatic pressure enhances the amplitude of the nonlinear contribution to the optical response of the multiple quantum well, whilst the linear one becomes reduced. Besides, the calculated coefficients are blueshifted due to the increasing of the applied electric field, and shows systematically dependence upon the hydrostatic pressure. The comparison of these results with those related with the consideration of a stationary spectrum of states in the heterostructure-obtained by placing infinite confining barriers at a conveniently far distance-shows essential differences in the pressure-induced effects in the sense of resonant frequency shifting as well as in the variation of the amplitudes of the optical responses.
