Coupling of atomic quadrupole transitions with resonant surface plasmons
Eng Aik Chan, Syed Abdullah Aljunid, Giorgio Adamo +3
We report on the coupling of an electric quadrupole transition in atom with plasmonic excitation in a nanostructured metallic metamaterial. The quadrupole transition at 685 nm in t…
Coherent light propagation through cold atomic clouds beyond the independent scattering approximation
Chang Chi Kwong, David Wilkowski, Dominique Delande +1
We calculate the relative permittivity of a cold atomic gas under weak probe illumination, up to second order in the density. Within the framework of a diagrammatic representation…
Dynamic polarizability measurements in Lu
K. J. Arnold, R. Kaewuam, T. R. Tan +3
We measure the differential polarizability of the Lu -to- clock transition at multiple wavelengths. This experimentally characterizes the differential…
Efficient microwave-to-optical conversion using Rydberg atoms
Thibault Vogt, Christian Gross, Jingshan Han +4
We demonstrate microwave-to-optical conversion using six-wave mixing in Rb atoms where the microwave field couples to two atomic Rydberg states, and propagates collinearly w…
Comparison of an efficient implementation of gray molasses to narrow-line cooling for the all-optical production of a lithium quantum gas
Christine L. Satter, Senmao Tan, Kai Dieckmann
We present an efficient scheme to implement a gray optical molasses for sub-Doppler cooling of Li atoms with minimum experimental overhead. To integrate the light for t…
Transmission spectroscopy of a single atom in the presence of tensor light shifts
Matthias Steiner, Yue-Sum Chin, Christian Kurtsiefer
We investigate the interplay between Zeeman and light shifts in the transmission spectrum of an optically trapped, spin-polarized Rubidium atom. The spectral shape of the transmiss…
