Professor Yossef Dothan Memorial Lecture: "Quantum Scattering Amplitudes For Classical Gravity"

Professor David Kosower is a Guest Lecturer at the Emilio Segre Distinguished Lectures in Physics, endowed by Raymond and Beverly Sackler for the academic year 2023/2024.

Abstract

The first gravitational wave observation by LIGO in 2015 spurred a new wave of interest by theorists in the calculations needed for current and future observatories. Theorists proposed new approaches based on quantum scattering amplitudes. In intervening years, this subject has turned into a flourishing activity within the Amplitudes community. I will explain the motivation for these approaches. I also present some examples of the many new `classical from quantum' approaches, and some of the future challenges.
