Continuous parametric feedback cooling of a single atom in an optical cavity
C. Sames, C. Hamsen, H. Chibani +3
We demonstrate a new feedback algorithm to cool a single neutral atom trapped inside a standing-wave optical cavity. The algorithm is based on parametric modulation of the confinin…
Two-Photon Blockade in an Atom-Driven Cavity QED System
Christoph Hamsen, Karl Nicolas Tolazzi, Tatjana Wilk +1
Photon blockade is a dynamical quantum-nonlinear effect that occurs in driven systems with an anharmonic excitation ladder. For a single atom strongly coupled to an optical cavity,…
Antiresonance phase shift in strongly coupled cavity QED
C. Sames, H. Chibani, C. Hamsen +3
We investigate phase shifts in the strong coupling regime of single-atom cavity quantum electrodynamics (QED). On the light transmitted through the system, we observe a phase shift…
Three-Photon Correlations in a Strongly Driven Atom-Cavity System
Markus Koch, Christian Sames, Maximilian Balbach +5
The quantum dynamics of a strongly driven, strongly coupled single-atom-cavity system is studied by evaluating time-dependent second- and third-order correlations of the emitted ph…
Feedback Cooling of a Single Neutral Atom
Markus Koch, Christian Sames, Alexander Kubanek +5
We demonstrate feedback cooling of the motion of a single rubidium atom trapped in a high-finesse optical resonator to a temperature of about 160 μK. Time-dependent transmission an…
Coherent excitation of a single atom to a Rydberg state
Y. Miroshnychenko, A. Gaëtan, C. Evellin +5
We present the coherent excitation of a single Rubidium atom to the Rydberg state (58d3/2) using a two-photon transition. The experimental setup is described in detail, as well as…
