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 …

Waveforms are classical observables associated with any radiative physical process. Using
scattering amplitudes, these are usually computed in a weak-field regime to some finite …

A bstract We show that large gauge transformations modify the structure of momentum
conservation leading to non-vanishing three-point amplitudes in a simple toy model of a …

The classic Abraham-Lorentz-Dirac self-force of pointlike particles is generalized within an
effective field theory setup to include linear spin and susceptibility effects described …

A particle moving with variable acceleration in the flat space-time affects the self-force due to
outgoing radiation. The gravitational fields bring an additional contribution to self-force due …

In odd space-time dimensions, the retarded solution of the massless wave equation has
support not only on the light cone, but also inside it. At the same time, a free massless field …

We consider a quantum scalar field on the classical background of an asymptotically anti–de
Sitter black hole and the backreaction the field's stress-energy tensor induces on the black …

Motivated by applications to the study of self-force effects in scalar-tensor theories of gravity,
we calculate the self-force exerted on a scalar charge in a circular orbit about a Reissner …

Electromagnetic and linear gravitational radiation do not solely propagate on the null cone
in 3+ 1 dimensions in curved spacetimes, contrary to their well-known behavior in flat …

The falling charge puzzle in gravitational field is well known due to the discussions of
radiation. The puzzle lies in the heart of linking the electromagnetism and gravity. Up to date …
