Testing general relativity in cosmology [PDF]
Living Reviews in Relativity, 2018 We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

Noncommutative General Relativity [PDF]
Physical Review D, 2005 We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommutative spacetimes to be volume-preserving transformations.

Landauer Principle and General Relativity [PDF]
Entropy, 2020 We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation.

Galaxies, 2014 A brief account of the present status of the recent nonlocal generalization of Einstein’s theory of gravitation is presented. The main physical assumptions that underlie this theory are described.

Conformally Coupled General Relativity
Universe, 2018 The gravity model developed in the series of papers (Arbuzov et al. 2009; 2010), (Pervushin et al. 2012) is revisited. The model is based on the Ogievetsky theorem, which specifies the structure of the general coordinate transformation group. The theorem

Nonlocal teleparallel cosmology [PDF]
European Physical Journal C: Particles and Fields, 2017 Even though it is not possible to differentiate general relativity from teleparallel gravity using classical experiments, it could be possible to discriminate between them by quantum gravitational effects. These effects have motivated the introduction of

General Relativity and Philosophy [PDF]
Journal of Philosophical Investigations, 2021 Is philosophy useful for physics? Many physicists and philosophers believe that it is; but there are those who challenge the usefulness of philosophy for science. Three major objections can be identified in their reasoning: 1.

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid
Physics Letters B, 2022 We establish the nonlocal generalization of the Israel-Stewart model for the relativistic causal thermodynamics of the cosmic fluid, which evolves in the homogeneous isotropic Universe.

European Physical Journal C: Particles and Fields, 2021 In the framework of the Einstein–Dirac-axion-aether theory we consider the quartet of self-interacting cosmic fields, which includes the dynamic aether, presented by the unit timelike vector field, the axionic dark mater, described by the pseudoscalar ...

Dynamic Aether as a Trigger for Spontaneous Spinorization in Early Universe
Universe, 2023 In the framework of the Einstein–Dirac-aether theory we consider a phenomenological model of the spontaneous growth of the fermion number, which is triggered by the dynamic aether.
