Quantum decoherence by Coulomb interaction

open access: yesNew Journal of Physics, 2020
The performance of modern quantum devices in communication, metrology or microscopy relies on the quantum–classical interaction which is generally described by the theory of decoherence.

Philosophical, Physical and Media Electron [PDF]

open access: yesIn Medias Res, 2019
In the contemporary age of everincreasing influence of electronic media as much as on an individual psyche as on the society as a whole, it would be of great value to undertake a detailed analysis of the very foundation of that means of communication ...

Electron-electron interactions in a weakly screened two-dimensional electron system [PDF]

open access: yesarXiv, 2002
We probe the strength of electron-electron interactions using magnetoconductivity measurements of two-dimensional non-degenerate electrons on liquid helium at 1.22 K. Our data extend to electron densities that are two orders of magnitude smaller than previously reported.

Monte Carlo study of medium-energy electron penetration in aluminium and silver

open access: yesNukleonika, 2015
Monte Carlo simulations are very useful for many physical processes. The transport of particles was simulated by Monte Carlo calculating the basic parameters such as probabilities of transmitted–reflected and angular-energy distributions after ...

A SIMPLIFIED LEAD CITRATE STAIN FOR USE IN ELECTRON MICROSCOPY

open access: yesJournal of Cell Biology, 1965
A disadvantage of the lead strains used in electron microscopy is the amount of time required for their preparation. One of the more stable and reliable stains, commonly called the lead citrate stain or Reynolds' stain (Reynolds, 1963), is made by mixing
