- Abstract summary: We calculate the dynamics of one and two two-level atoms interacting with the electromagnetic vacuum field in the vicinity of an optical nanofiber.
Despite the non-trivial environment, we discuss the validity of approximating the speed of atom-atom communication to the group velocity of the guided field.

- Abstract: We calculate the dynamics of one and two two-level atoms interacting with the
electromagnetic vacuum field in the vicinity of an optical nanofiber without
making either the Born or the Markov approximations. We use a constant
dielectric function and the Drude-Lorentz model, observing deviations from the
standard super- and sub-radiant decays. Despite the non-trivial environment
correlations, we discuss the validity of approximating the speed of atom-atom
communication to the group velocity of the guided field. Our work presents a
deeper understanding of the validity of commonly used approximations in recent
platforms for quantum optics applications in the context of waveguide QED.
