A semiclassical approach reproducing asymptotically the Heitler formula for atomic photoionization
Учёные 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 ...

Improved scenario of baryogenesis [PDF]
arXiv, 1999 It is assumed that, in the primordial plasma, at the temperatures above the mass of electron, fermions are in the neutral state being the superposition of particle and antiparticle. There exists neutral proton-electron symmetry. Proton-electron equilibrium is defined by the proton-electron mass difference.

OVERVIEW OF X-RAY FLUORESCENCE SPECTROMETRY [PDF]
Fiabilitate şi Durabilitate, 2021 One of the techniques used in identifying the constituent chemical elements of a material is the X-ray fluorescence method. From the analysis of X-ray fluorescence data the energy and intensity of the characteristic photons emitted by the sample can be

Quantum decoherence by Coulomb interaction
New 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.

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

Philosophical, Physical and Media Electron [PDF]
In 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-phonon coupling in correlated materials: insights from the Hubbard-Holstein model [PDF]
arXivDynamical mean-field theory computations of the electron self energy of the Hubbard-Holstein model as a function of electron-phonon and electron-electron interactions are analyzed to gain insight into the dependence of electron-phonon couplings on correlation strength in quantum materials.
