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…
Polarization gradient cooling of single atoms in optical dipole traps
Yue-Sum Chin, Matthias Steiner, Christian Kurtsiefer
We experimentally investigate - polarization gradient cooling~(PGC) of a single Rb atom in a tightly focused dipole trap and show that the cooling limit strongly d…
Single atoms coupled to a near-concentric cavity
Chi Huan Nguyen, Adrian Nugraha Utama, Nick Lewty +5
Concentric cavities can lead to strong photon-atom coupling without a need for high finesse or small physical-cavity volume. In a proof-of-principle experiment of this concept we d…
Nonlinear photon-atom coupling with 4Pi microscopy
Yue-Sum Chin, Matthias Steiner, Christian Kurtsiefer
Implementing nonlinear interactions between single photons and single atoms is at the forefront of optical physics. Motivated by the prospects of deterministic all-optical quantum…
Photon bandwidth dependence of light-matter interaction
Matthias Steiner, Victor Leong, Mathias Alexander Seidler +2
We investigate the scattering of single photons by single atoms and, in particular, the dependence of the atomic dynamics and the scattering probability on the photon bandwidth. We…
Quantifying the role of thermal motion in free-space light-atom interaction
Yue-Sum Chin, Matthias Steiner, Christian Kurtsiefer
We demonstrate 17.7(1)% extinction of a weak coherent field by a single atom. We observe a shift of the resonance frequency and a decrease in interaction strength with the external…
