Quantum spin dynamics in external classical fields [PDF]
EPJ Web of Conferences, 2019 We study the quantum and classical dynamics of spinning particles in the framework of the general-relativistic covariant Dirac theory. The exact Foldy-Wouthuysen transformation for the most general case of a fermion in arbitrary configurations of the ...

Creation of a system for automatic monitoring of electromagnetic effects on biological and technical systems [PDF]
BIO Web of Conferences, 2022 Using a digital “twin” of a convergent biological and technical supersystem of a certain region to develop measures to ensure environmental safety is because of the need to analyze and predict processes and the level of electromagnetic pollution of the ...

Electromagnetic Transients in Multiconductor Transmission Lines
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022 The theory of multiconductor transmission lines is based on the principle of superposition. According to this principle, any electric or magnetic field can be represented as the sum of individual electric or magnetic fields.

Reports in Advances of Physical Sciences, 2022 Fascinated people from the dawn of history, gravity is not understood, still. Here, we suggest that gravity is a result of a process in the material: (1) Gravitational photons are produced by all atoms that exist in nonzero temperature and or interact ...

General relativistic theory of gravity and electricity
Revista de Investigación de Física, 2022 As gravitation and electromagnetism are closely analogous long-range interactions, and the current formulation of gravitation is given in terms of geometry, we expect the latter also to appear throug the geometry.

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret
Advanced Functional Materials, EarlyView.Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Electromagnetic energy density in hyperbolic metamaterials
Scientific Reports, 2022 We present the theory of electromagnetic energy propagation through a dispersive and absorbing hyperbolic metamaterial (HMM). In this way, the permittivity tensor components of HMM (especially, nanowire HMM) may appear to be hopeless, but as a non ...
