@inproceedings{Hoskins2021AnalysisOS, title={Analysis of single-excitation states in quantum optics}, author={Jeremy G. Hoskins and Jason Kaye and Manas Rachh and John C. Schotland}, year={2021} }
In this paper we analyze the dynamics of single-excitation states, which model the scattering of a single photon from multiple two level atoms. For short times and weak atom-field couplings we show that the atomic amplitudes are given by a sum of decaying exponentials, where the decay rates and Lamb shifts are given by the poles of a certain analytic function. This result is a refinement of the “pole approximation” appearing in the standard Wigner-Weisskopf analysis of spontaneous emission. On…

This work considers the numerical solution of a nonlocal partial differential equation which models the process of collective spontaneous emission in a two-level atomic system containing a single photon, and describes an efficient solver for the case of a Gaussian atomic density.
Deviations from exponential decay in the case of spontaneous emission from a two-level atom.

A mathematically rigorous treatment of the Weisskopf-Wigner model of atomic spontaneous emission is presented and it is shown that in the correct asymptotic treatment with a cutoff frequency at which the dipole approximation breaks down, the main contribution to the long-time deviation from the exponential decay is of the order of 1.

Abstract. We consider the lattice analog of a recently proposed continuum model for the propagation of oneand two-photon states in a random medium. We find that there is localization of single…

The coherent and reversible mapping of a light field with less than one photon per pulse onto an ensemble of ∼107 atoms naturally trapped in a solid is demonstrated by coherently absorbing the light field in a suitably prepared solid-state atomic medium.
