Measurement Theory and General Relativity [PDF]
The theory of measurement is employed to elucidate the physical basis of general relativity. For measurements involving phenomena with intrinsic length or time scales, such scales must in general be negligible compared to the (translational and ...

Electromagnetic Properties of Neutrinos
In this paper, we discuss the main theoretical aspects and experimental effects of neutrino electromagnetic properties. We start with a general description of the electromagnetic form factors of Dirac and Majorana neutrinos.

We introduce the electromagnetic-gravitational coupling in the Hořava–Lifshitz framework, in $$3+1$$ 3+1 dimensions, by considering the Hořava–Lifshitz gravity theory in $$4+1$$ 4+1 dimensions at the kinetic conformal point and then performing a Kaluza ...

We derive weak turbulence and quasilinear models for relativistic charged particle dynamics in pitch-angle and energy space, due to interactions with electromagnetic waves propagating (anti-)parallel to a uniform background magnetic field.

Relativistic x-ray free-electron lasers in the quantum regime [PDF]
We present a nonlinear theory for relativistic x-ray free-electron lasers in the quantum regime, using a collective Klein-Gordon (KG) equation (for relativistic electrons), which is coupled with the Maxwell-Poisson equations for the electromagnetic and ...

Several studies focusing on the anomalies of one specific parameter (such as magnetic, ionospheric, radon release, temperature, geodetic, etc.) before impending earthquakes are constantly challenged because their results can be regarded as noise, false ...

The Spatial Singularity Expansion Method for Electromagnetics
We develop a general singularity expansion method (SEM) focused on the spatial structure of electromagnetic fields and currents. In contrast to the traditional temporal SEM, where complex analytical continuation is performed on the forward Green's ...

Quantum spin dynamics in external classical fields [PDF]
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]
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
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.
