Recent progress on nonlinear properties of parity-time (PT)-symmetric systems is
comprehensively reviewed in this article. PT symmetry started out in non-Hermitian quantum …

We review the effective field theory (EFT) approach to gravitational dynamics. We focus on
extended objects in long-wavelength backgrounds and gravitational wave emission from …

We obtain the total impulse in the scattering of nonspinning binaries in general relativity at
fourth post-Minkowskian order, ie, O (G 4), including linear, nonlinear, and hereditary …

Using the N= 1 supersymmetric, spinning worldline quantum field theory formalism, we
compute the conservative spin-orbit part of the momentum impulse Δ pi μ, spin kick Δ S i μ …

A bstract A precise link is derived between scalar-graviton S-matrix elements and
expectation values of operators in a worldline quantum field theory (WQFT), both used to …

A bstract We extend the Post-Minkowskian (PM) effective field theory (EFT) approach to
incorporate conservative and dissipative radiation-reaction effects in a unified framework …

A bstract We describe the formalism to compute gravitational-wave observables for compact
binaries via the effective field theory framework in combination with modern tools from …

A bstract We study classical radiation fields at next-to-leading order using the methods of
scattering amplitudes. The fields of interest to us are sourced when two massive, point-like …

This review article presents the progress made over the last decade, since the introduction
of effective field theories (EFTs) into post-Newtonian (PN) gravity. These have been put …

A bstract We extend the boundary-to-bound (B2B) correspondence to incorporate radiative
as well as conservative radiation-reaction effects. We start by deriving a map between the …
