Self-force and radiation reaction in general relativity [PDF]

open access: yesReports on progress in physics. Physical Society, 2018
The detection of gravitational waves from binary black-hole mergers by the LIGO–Virgo Collaboration marks the dawn of an era when general-relativistic dynamics in its most extreme manifestation is directly accessible to observation.

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 ...

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 ...

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.

Noncommutative General Relativity [PDF]

open access: yes, 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.

General Relativity from Scattering Amplitudes. [PDF]

open access: yesPhysical Review Letters, 2018
Weoutline the program to apply modern quantum field theory methods to calculate observables in classical general relativity through a truncation to classical terms of the multigraviton, two-body, on-shell scattering amplitudes between massive fields ...

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.

Tests of General Relativity with GW170817. [PDF]

open access: yesPhysical Review Letters, 2018
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source.

Symmetries and charges of general relativity at null boundaries [PDF]

open access: yesJournal of High Energy Physics, 2018
We study general relativity at a null boundary using the covariant phase space formalism. We define a covariant phase space and compute the algebra of symmetries at the null boundary by considering the boundary-preserving diffeomorphisms that preserve ...
