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'.

Is the Axionic Dark Matter an Equilibrium System?

open access: yesUniverse, 2020
We consider an axionic dark matter model with a modified periodic potential for the pseudoscalar field in the framework of the axionic extension of the Einstein-aether theory.

RELATIVE LOCALITY: A DEEPENING OF THE RELATIVITY PRINCIPLE [PDF]

open access: yesInternational Journal of Modern Physics D, 2011
We describe a recently introduced principle of relative locality which we propose governs a regime of quantum gravitational phenomena accessible to experimental investigation. This regime comprises phenomena in which ℏ and GN may be neglected, while their ratio, the Planck mass [Formula: see text], is important. We propose that Mp governs the scale at

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 ...

Spontaneous Color Polarization as A Modus Originis of the Dynamic Aether

open access: yesUniverse, 2020
We suggest the phenomenological model of emergence of the dynamic aether as a result of decay of the SU(N) symmetric field configuration containing the multiplet of vector fields.

Study of Spectral State Transitions in Black Hole Binaries

open access: yesThe Astrophysical Journal, 2023
The aim of our work is to study the origin of the spectral transitions of transient black hole binaries. In this work, we find signatures of spectral state transition (hard to soft state) while studying the radiative shock for the accretion flow.

The Relativity of Indeterminacy

open access: yesEntropy, 2021
A long-standing tradition, largely present in both the physical and the philosophical literature, regards the advent of (special) relativity—with its block-universe picture—as the failure of any indeterministic program in physics. On the contrary, in this paper, we note that upholding reasonable principles of finiteness of information hints at a ...

Relative thermalization [PDF]

open access: yesPhysical Review E, 2016
When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is "when does a system thermalize relative to a particular reference?" By relative thermalization we mean that, as well as being in a ...

From Modified Newtonian Dynamics to Superfluid Vacuum Theory

open access: yesEntropy, 2022
Herein is a review of the essentials of Modified Newtonian Dynamics (MOND) versus dark matter models based on Superfluids for modeling galactic rotation curves. We review the successes and issues of both approaches.
