It is shown that at low densities, quantum dots with few electrons may be mapped onto effective charge-spin models for the low-energy eigenstates. This is justified by defining a lattice model based on a many-electron pocketstate basis in which electrons are localised near their classical ground-state positions. The equivalence to a single-band Hubbard model is then established leading to a cha...

A comprehensive analysis of the effects of Geant4 algorithms for condensed transport in detectors is in progress. The first phase of the project focuses on electron multiple scattering, and studies two related observables: the longitudinal pattern of energy deposition in various materials, and the fraction of backscattered particles. The quality of the simulation is evaluated through comparison...

Abstract The TRISTAN project is the upgrade of KATRIN experiment designed for search sterile neutrinos by replacing current detector with a multipixel SDD (Silicon Drift Detector) matrix. We have characterized SDDs response to electrons using SEM (Scanning Electron Microscope) as an electron source and Geant4-based simulation whose output processed empirical function reproduce data. crosschecke...

OBJECTIVE The authors describe a consistent theoretical model of the cellular energy transfer (respiratory chain) by taking into consideration the radiation phenomena of electrons and therapeutic low level laser. SUMMARY BACKGROUND DATA Biochemical models of the cellular energy transfer regard the classical corpuscular aspect of electrons as the responsible energy carriers, thereby ignoring t...
