Amplitudes for Hawking Radiation

Donal O'Connell

University of Edinburgh

In recent years, ideas from quantum field theory, including effective field theory and the on-shell methods of scattering amplitude, have been successfully applied to classical gravitational-wave physics. In this talk, I will show that these ideas extend to the semiclassical case of Hawking radiation. Along the way, I will discuss the relationship between Bogoliubov coefficients and generalised amplitudes.
