Electronic Markets and Electronic Hierarchies [PDF]

open access: yesCommunications of the ACM, 1987
Abstract The innovations in information technologies of the past two decades have radically reduced the time and cost of processing and communicating information. These reductions have in turn brought many changes in the ways that tasks are accomplished in firms.

Electron–electron and electron–hole pairing in graphene structures [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
The superconducting pairing of electrons in doped graphene owing to in-plane and out-of-plane phonons is considered. It is shown that the structure of the order parameter in the valley space substantially affects conditions of the pairing. Electron–hole pairing in a graphene bilayer in the strong coupling regime is also considered.

A semiclassical approach reproducing asymptotically the Heitler formula for atomic photoionization

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The wave-corpuscle method for description of atomic photoionization by a flux of photons in the visible and X-ray range was developed and applied. Using the calculated photoionization probability in the asymptotics, we obtained the desired approximate ...

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.

Photoluminescence and thermoluminescence in a Li2SO4 crystall

open access: yesEurasian Journal of Physics and Functional Materials, 2022
The nature of intrinsic emission and the creation of electron-hole trapping centers in irradiated with ultraviolet and X-rays at 15 K and 300 K was investigated in Li2SO4 by methods of spectroscopy. It is shown that in activated Li2 SO4 with an energy of

On the Diffusion Rates of Electron Bounce Resonant Scattering by Magnetosonic Waves

open access: yesGeophysical Research Letters, 2018
Magnetosonic waves have been demonstrated as effective for bounce resonant scattering. Electron scattering rates due to bounce resonance interaction with magnetosonic waves are derived in a general form, where the effects of the finite Larmor radius, of ...

Correlated Electron Transport in Molecular Electronics [PDF]

open access: yesPhysical Review Letters, 2004
Theoretical and experimental values to date for the resistances of single molecules commonly disagree by orders of magnitude. By reformulating the transport problem using boundary conditions suitable for correlated many-electron systems, we approach electron transport across molecules from a new standpoint.

Efficacy of Chelating Agents on Calcium Hydroxide Removal from the Root Canals and their Influence on the Penetration of a Bioceramic Sealer: An In-vitro Evaluation [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Eliminating Calcium Hydroxide {Ca(OH)2 } remnants from root canal walls presents a significant challenge. Nevertheless, its complete removal enhances the deeper penetration of a sealer, which improves the three-dimensional (3D ...
