In a recent paper "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons" [Astrophys. Space Sci. 338, 271-278 (2012)] Eslami, Mottaghizadeh and Pakzad deal ...
The fabrication and operation of V-based superconducting nanorefrigerators is reported. Speci cally, electrons in an Al island are cooled thanks to hot-quasiparticle extraction provided by tunnel-coup...
A fractal-like alignment of quantum wells is shown to accommodate resonant states with long lifetimes. For the parameters of the semiconductor heterostructure GaAs/Al$_{0.4}$Ga$_{0.6}$As with the wel...
Physicists have used holography to reliably do to electrons what they can already do to photons – twist the particle wavefronts to create beams with vortices at their centre. The researchers say that ...
Researchers in Germany and the US have used flashes of laser light to follow the motion of valence electrons as they are excited and ejected from atoms of krypton. They say that their technique could ...
An exotic type of symmetry - suggested by string theory and theories of high-energy particle physics, and also conjectured for electrons in solids under certain conditions - has been observed experime...
The phenomenon of the acceleration of the (perturbing) electrons by the ion field (AEIF) significantly reduces Stark widths and shifts in plasmas of relatively high densities and/or relatively low tem...
Undulators are key devices to produce brilliant synchrotron radiation at the synchrotron radiation facilities. In this paper we present a numerical computing method, including the computing program t...
November 17, 2006,Troy Van Voorhis likes to watch how things work. This natural curiosity led to his current research on the behavior of electrons and how they function in various molecular systems, i...
Numerical calculations are shown to reproduce the main results of recent experiments involving nonlocal spin control in nanostructures (N. J. Craig et al., Science 304, 565 (2004)). In particular, the...
A problem of two electrons spatially separated in vertically coupled one-dimensional rings is solved exactly by using the numerical trigonometric sweep method. The change of the level-ordering and the...
In this article we study the electronic transport through a triple quantum–dot molecule parallel–coupled to leads under a magnetic field. Analytical expressions are obtained for both the conductance a...
The effect of number of particles on the physical properties of a two dimensional parabolic quantum dot system is investigated numerically at finite temperature. The Thomas-Fermi equation is solved se...
Modern semiconductor technologies have made possible special devices in which a gradual dimensional crossover may be induced by means of applied electric fields. Two specific examples are described. T...
In this work we have studied the direct detection and spectrometric capabilities for internal conversion electrons of an ion-implanted diode, developed in the framework of R&D programs at CERN, envisa...
