Effective Field Theory of Gravity in Relativistic Media
Beka Modrekiladze
We develop an effective field theory of gravity in relativistic media. Integrating out the medium leaves vacuum gravity with updated Feynman rules: a graviton propagator dressed by…

A Unified Treatment of the Self-Force Problem
Beka Modrekiladze, Ira Z. Rothstein, Jordan Wilson-Gerow
This paper introduces formalism, based on worldline effective field theory, which allows one to systematically calculate the gravitational self-force on a compact object immersed i…

A fast, differentiable neural-network surrogate for precessing binary black-hole waveforms
Beka Modrekiladze
Gravitational-wave parameter estimation requires millions of waveform evaluations per event, a cost that constrains real-time inference and population studies. We present a fast, f…
