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 $R^{1+\delta}$. This scale-free extension reduces to general relativity when $\delta \to 0$.

Coincident general relativity [PDF]

open access: yesPhysical Review D, 2017
The Palatini's device is applied to generate teleparallel and symmetric teleparallel theories of gravity. From the latter is discovered an exceptional class which is consistent with a vanishing affine connection.

Traversable Wormholes in General Relativity. [PDF]

open access: yesPhysical Review Letters, 2021
Blázquez-Salcedo et al. [Phys. Rev. Lett. 126, 101102 (2021)PRLTAO0031-900710.1103/PhysRevLett.126.101102] obtained asymptotically flat traversable wormhole solutions in the Einstein-Dirac-Maxwell theory without using phantom matter.

General Relativity and Philosophy [PDF]

open access: yesJournal 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.

Numerical Hydrodynamics in General Relativity [PDF]

open access: yesLiving Reviews in Relativity, 2000
The current status of numerical solutions for the equations of ideal general relativistic hydrodynamics is reviewed. Different formulations of the equations are presented, with special mention of conservative and hyperbolic formulations well-adapted to ...

Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog [PDF]

open access: yes, 2020
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the consistency of the data with predictions from the theory. We first establish

Energy conditions in general relativity and quantum field theory [PDF]

open access: yesClassical and quantum gravity, 2020
This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results and applications, complemented with a few new derivations and discussions.

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid

open access: yesPhysics 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.

Interaction of the axionic dark matter, dynamic aether, spinor and gravity fields as an origin of oscillations of the fermion effective mass

open access: yesEuropean 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 ...
