# Light Scattering from Solid-State Quantum Emitters: Beyond the Atomic Picture

## TL;DR

This paper investigates how solid-state quantum emitters, specifically quantum dots, scatter light differently from atomic systems due to phonon interactions, revealing unique effects like phonon sidebands and non-atomic behavior.

## Contribution

It develops a comprehensive model of light scattering from solid-state emitters that includes phonon interactions, extending beyond the traditional atomic picture.

## Key findings

- Phonon coupling causes a sideband insensitive to excitation conditions.
- Non-monotonic relationship between laser detuning and coherent scattering.
- Deviations from atom-like behavior in solid-state quantum emitters.

## Abstract

Coherent scattering of light by a single quantum emitter is a fundamental process at the heart of many proposed quantum technologies. Unlike atomic systems, solid-state emitters couple to their host lattice by phonons. Using a quantum dot in an optical nanocavity, we resolve these interactions in both time and frequency domains, going beyond the atomic picture to develop a comprehensive model of light scattering from solid-state emitters. We find that even in the presence of a cavity, phonon coupling leads to a sideband that is completely insensitive to excitation conditions, and to a non-monotonic relationship between laser detuning and coherent fraction, both major deviations from atom-like behaviour.
