# Effective Field Theories of Post-Newtonian Gravity

#### Effective Field Theories of Post-Newtonian Gravity

- Event time: 2:00pm
- Event date: 16th January 2019
- Speaker: Dr Michele Levi (Institut de Physique Thorique)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

This talk presents the progress made in my research via the introduction of effective field theories (EFTs) into post-Newtonian (PN) Gravity.

These have been put forward in the context of gravitational waves (GWs) from the compact binary inspiral.

The setup and the strategy of a multi-stage EFT framework, which is deployed for the PN binary inspiral problem, is outlined.

I then present in more detail the study of two effective theories at the intermediate scales of the problem.

First, the EFT for a single rotating compact object is considered, from which I proceed to the EFT of a compact binary system,

viewed as a composite particle with internal binding interactions.

I conclude with the prospects of building on the field, and using further modern field theory insights and tools, to address the study of GWs,

as well as to expand our fundamental understanding of QFTs and Gravity theories at all scales.
