Towards Multifractality through an Ernst-Type Potential in Complex Systems Dynamics

open access: yesEntropy, 2023
Some possible correspondences between the Scale Relativity Theory and the Space–Time Theory can be established. Since both the multifractal Schrödinger equation from the Scale Relativity Theory and the General Relativity equations for a gravitational ...

Einstein–Maxwell-axion theory: dyon solution with regular electric field

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In the framework of the Einstein–Maxwell-axion theory we consider static spherically symmetric solutions which describe a magnetic monopole in the axionic environment.

Birefringence induced by pp-wave modes in an electromagnetically active dynamic aether

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In the framework of the Einstein–Maxwell-aether theory we study the birefringence effect, which can occur in the pp-wave symmetric dynamic aether. The dynamic aether is considered to be a latently birefringent quasi-medium, which displays this hidden ...

Carroll Expansion of General Relativity

open access: yesSciPost Physics, 2022
We study the small speed of light expansion of general relativity, utilizing the modern perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll limit, in which light cones close up. To this end, we first rewrite the

Curvature Dynamics in General Relativity

open access: yesUniverse, 2023
The equations of general relativity are recast in the form of a wave equation for the Weyl tensor. This allows reformulation of gravitational wave theory in terms of curvature waves, rather than metric waves.

What is General Relativity? [PDF]

open access: yes, 2017
General relativity is a set of physical and geometric principles, which lead to a set of (Einstein) field equations that determine the gravitational field, and to the geodesic equations that describe light propagation and the motion of particles on the ...
