On the need for soft dressing
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
In order to deal with IR divergences arising in QED or perturbative quantum gravity scattering processes, one can either calculate inclusive quantities or use dressed asymptotic st…
Dressed infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We study information-theoretic aspects of the infrared sector of quantum electrodynamics, using the dressed-state approach pioneered by Chung, Kibble, Faddeev-Kulish and others. In…
Infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved so…
Scattering with partial information
Daniel Carney, Laurent Chaurette, Gordon Semenoff
We study relativistic scattering when one only has access to a subset of the particles, using the language of quantum measurement theory. We give an exact, non-perturbative formula…
