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…
On the Motion of Compact Objects in Relativistic Viscous Fluids
Beka Modrekiladze, Ira Z. Rothstein, Jordan Wilson-Gerow
We present a world-line effective field theory of compact objects moving relativistically through a viscous fluid. The theory is valid when velocity gradients are small compared to…
Transfer Learning Adapts to Changing PSD in Gravitational Wave Data
Beka Modrekiladze
The detection of gravitational waves has opened unparalleled opportunities for observing the universe, particularly through the study of black hole inspirals. These events serve as…
Probing the Information-Probabilistic Description
Merab Gogberashvili, Beka Modrekiladze
The information conservation principle is probed for classically isolated systems, like the Hubble sphere and black holes, for which the rise of entanglement entropy across their h…
