Propagation of charged particle waves in a uniform magnetic field
Christian Bracher, Arnulfo Gonzalez
This paper considers the probability density and current distributions generated by a point-like, isotropic source of monoenergetic charges embedded into a uniform magnetic field e…
New Mathematical Tools for Quantum Technology
Christian Bracher, Manfred Kleber, Tobias Kramer
Progress in manufacturing technology has allowed us to probe the behavior of devices on a smaller and faster scale than ever before. With increasing miniaturization, quantum effect…
The photoelectric effect in external fields
Christian Bracher, John B. Delos, Vassiliki Kanellopoulos +2
Atoms and negative ions interacting with laser photons yield a coherent source of photoelectrons. Applying external fields to photoelectrons gives rise to interesting and valuable…
Electron dynamics in parallel electric and magnetic fields
Christian Bracher, Tobias Kramer, John B. Delos
We examine the spatial distribution of electrons generated by a fixed energy point source in uniform, parallel electric and magnetic fields. This problem is simple enough to permit…
Electron propagation in crossed magnetic and electric fields
Tobias Kramer, Christian Bracher, Manfred Kleber
Laser-atom interaction can be an efficient mechanism for the production of coherent electrons. We analyze the dynamics of monoenergetic electrons in the presence of uniform, perpen…
Ballistic matter waves with angular momentum: Exact solutions and applications
Christian Bracher, Tobias Kramer, Manfred Kleber
An alternative description of quantum scattering processes rests on inhomogeneous terms amended to the Schroedinger equation. We detail the structure of sources that give rise to m…
Matter waves from quantum sources in a force field
Tobias Kramer, Christian Bracher, Manfred Kleber
Localized scattering phenomena may result in the formation of stationary matter waves originating from a compact region in physical space. Mathematically, such waves are advantageo…
Four-path interference and uncertainty principle in photodetachment microscopy
Tobias Kramer, Christian Bracher, Manfred Kleber
We study the quantal motion of electrons emitted by a pointlike monochromatic isotropic source into parallel uniform electric and magnetic fields. The two-path interference pattern…
