Analysis of the near-resonant fluorescence spectra of a single rubidium atom localized in a three-dimensional optical lattice

TL;DR

This paper discusses the near-resonant fluorescence spectra of a single rubidium atom in a 3D optical lattice, focusing on matter-wave tunneling effects in a strong Lamb-Dicke regime.

Contribution

It provides supplementary analysis on matter-wave tunneling-induced broadening in the spectra of a single atom in an optical lattice.

Findings

Identification of tunneling-induced spectral broadening

Analysis of the Lamb-Dicke regime effects

Insights into atom localization in optical lattices

Abstract

Supplementary information is presented on the recent work by W. Kim et al. on the matter-wave-tunneling-induced broadening in the near-resonant spectra of a single rubidium atom localized in a three-dimensional optical lattice in a strong Lamb-Dicke regime.
