Theoretical Physics Colloquium

Angular Momentum Radiation

by Prof. Aneesh Manohar (University of California San Diego, USA)

Tuesday, April 16, 2024 from to (Asia/Kolkata)
at AG69 and on zoom
Description
I will discuss angular momentum radiation in electromagnetism and gravitation. I will first discuss angular momentum radiation in electromagnetism, and point out some subtleties relative to energy and momentum radiation. I will then discuss a recent calculation of the angular momentum loss in gravitational binary systems to order G^2 and G^3, and to all orders in velocity. This calculation is relevant for the analysis of gravitational binary orbits being studied by LIGO and Advanced LIGO.
