DOI: 10.1007/jhep04(2022)097
Abstract: Abstract We present two novel results about the universal structure of radiative QED amplitudes in the soft and in the collinear limit. On the one hand, we extend the well-known Low-Burnett-Kroll theorem to the one-loop… read more here.

Abstract: As a toy model for QED in strong background fields, we consider the impact of backreaction and loop effects on scattering processes in quantum optics. We show that neglecting backreaction misses qualitative and quantitative features… read more here.

Abstract: We investigate the worldline quantum field theory (WQFT) formalism for scalar-QED and observe that a generating function emerges from WQFT, from which the scattering angle ensues. This generating function bears important similarities with the radial… read more here.

DOI: 10.1103/physrevd.95.114508
Abstract: The simulation of lattice gauge theories with tensor network (TN) methods is becoming increasingly fruitful. The vision is that such methods will, eventually, be used to simulate theories in $(3+1)$ dimensions in regimes difficult for… read more here.
