Regularised Arbitrary Gauge non-Relativistic QED
Alex Chivers-White, Adam Stokes
We develop a regularised arbitrary-gauge formulation of nonrelativistic quantum electrodynamics and use it to compare Coulomb and multipolar descriptions with a Lorentzian form fac…

The role of polarization field terms in a model for a cavity quantum material
Arwen Lloyd, Adam Stokes, Alessandro Principi +1
Constructing models for cavity quantum materials requires a careful treatment of the light-matter coupling. In general, one must specify matrix elements constructed from the materi…
