Classical worldlines from scattering amplitudes
Zeno Capatti, Mao Zeng
We present a systematic diagrammatic investigation of the classical limit of observables computed from scattering amplitudes in quantum field theory through the Kosower-Maybee-O'Co…

Universal corrections to the superfluid gap in a cold Fermi gas
Silas R. Beane, Zeno Capatti, Roland C. Farrell
A framework for computing the superfluid gap in an effective field theory (EFT) of fermions interacting via momentum-independent contact forces is developed. The leading universal…
