Classical Gravitational Bremsstrahlung from a Worldline Quantum Field Theory
Gustav Uhre Jakobsen, Gustav Mogull, Jan Plefka +1
Using the recently established formalism of a worldline quantum field theory (WQFT) description of the classical scattering of two spinless black holes, we compute the far-field ti…

Classical black hole scattering from a worldline quantum field theory
Gustav Mogull, Jan Plefka, Jan Steinhoff
A precise link is derived between scalar-graviton S-matrix elements and expectation values of operators in a worldline quantum field theory (WQFT), both used to describe classical…

Unraveling conformal gravity amplitudes
Henrik Johansson, Gustav Mogull, Fei Teng
Conformal supergravity amplitudes are obtained from the double-copy construction using gauge-theory amplitudes, and compared to direct calculations starting from conformal supergra…
