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 ...

The power of general relativity [PDF]

open access: yesPhysical Review D, 2005
We study the cosmological and weak-field properties of theories of gravity derived by extending general relativity by means of a Lagrangian proportional to $R^{1+δ}$. This scale-free extension reduces to general relativity when $δ\to 0$. In order to constrain generalisations of general relativity of this power class we analyse the behaviour of the ...

Post-Minkowskian Hamiltonians in general relativity [PDF]

open access: yesPhysical Review D, 2019
We describe the computation of post-Minkowskian Hamiltonians in General Relativity from scattering amplitudes. Using a relativistic Lippmann-Schwinger equation, we relate perturbative amplitudes of massive scalars coupled to gravity to the post ...

Why Einstein did not believe that General Relativity geometrizes gravity [PDF]

open access: yes, 2013
I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or (subsequently) the electromagnetic field; indeed, he thought that the very statement that General Relativity geometrizes gravity "is not saying anything

Tests of general relativity with the binary black hole signals from the LIGO-Virgo catalog GWTC-1 [PDF]

open access: yes, 2019
The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronomical observations and laboratory tests.

A systematic approach to generalisations of General Relativity and their cosmological implications [PDF]

open access: yesPhysics reports, 2018
A century ago, Einstein formulated his elegant and elaborate theory of General Relativity, which has so far withstood a multitude of empirical tests with remarkable success.

About the origins of the general theory of relativity: Einstein's search for the truth [PDF]

open access: yes, 2005
On the 20th June 1933 Professor Einstein addressed a large and enthusiastic audience in the Victorian Gothic Bute Hall of the University of Glasgow. Einstein spoke 'About the Origins of the General Theory of Relativity'.

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.
