The effective field theorist's approach to gravitational dynamics

RA Porto - Physics Reports, 2016 - Elsevier
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 …

Effective field theories of post-Newtonian gravity: a comprehensive review

M Levi - Reports on Progress in Physics, 2020 - iopscience.iop.org
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 …

Effective field theory of dissipative fluids

M Crossley, P Glorioso, H Liu - Journal of High Energy Physics, 2017 - Springer
A bstract We develop an effective field theory for dissipative fluids which governs the
dynamics of long-lived gapless modes associated with conserved quantities. The resulting …

Conservative dynamics of binary systems to fourth post-Newtonian order in the EFT approach. II. Renormalized Lagrangian

S Foffa, RA Porto, I Rothstein, R Sturani - Physical Review D, 2019 - APS
We complete the derivation of the conservative dynamics of binary systems to fourth Post-
Newtonian (4PN) order in the effective field theory (EFT) approach. We present a self …

Contact hamiltonian mechanics

A Bravetti, H Cruz, D Tapias - Annals of Physics, 2017 - Elsevier
In this work we introduce contact Hamiltonian mechanics, an extension of symplectic
Hamiltonian mechanics, and show that it is a natural candidate for a geometric description of …

Tail effect in gravitational radiation reaction: Time nonlocality and renormalization group evolution

CR Galley, AK Leibovich, RA Porto, A Ross - Physical Review D, 2016 - APS
We use the effective field theory (EFT) framework to calculate the tail effect in gravitational
radiation reaction, which enters at the fourth post-Newtonian order in the dynamics of a …

A minimization principle for incompressible fluid mechanics

H Taha, C Gonzalez, M Shorbagy - Physics of Fluids, 2023 - pubs.aip.org
Most variational principles in classical mechanics are based on the principle of least action,
which is only a stationary principle. In contrast, Gauss' principle of least constraint is a true …

[HTML][HTML] A tale of tails through generalized unitarity

A Edison, M Levi - Physics Letters B, 2023 - Elsevier
We introduce a novel framework to study high-order gravitational effects on a binary from the
scattering of its emitted gravitational radiation. Here we focus on the radiation-reaction due …

Higher-order tails and RG flows due to scattering of gravitational radiation from binary inspirals

A Edison, M Levi - Journal of High Energy Physics, 2024 - Springer
A bstract We establish and develop a novel methodology to treat higher-order non-linear
effects of gravitational radiation that is scattered from binary inspirals, which employs …

Minimizing Nature's Cost: Exploring Data-Free Physics-Informed Neural Network Solvers for Fluid Mechanics Applications
