Collective suppression of optical hyperfine pumping in dense clouds of atoms in microtraps
Shimon Machluf, Julian B. Naber, Maarten L. Soudijn +2
We observe a density-dependent collective suppression of optical pumping between the hyperfine ground states in an array of submicrometer-sized clouds of cold rubidium atoms. The s…
Trapping of Rydberg Atoms in Tight Magnetic Microtraps
A. G. Boetes, R. V. Skannrup, J. B. Naber +2
We explore the possibility to trap Rydberg atoms in tightly confining magnetic microtraps. The trapping frequencies for Rydberg atoms are expected to be influenced strongly by magn…
Controlling Stray Electric Fields on an Atom Chip for Rydberg Experiments
D. Davtyan, S. Machluf, M. L. Soudijn +4
Experiments handling Rydberg atoms near surfaces must necessarily deal with the high sensitivity of Rydberg atoms to (stray) electric fields that typically emanate from adsorbates…
Raman transitions between hyperfine clock states in a magnetic trap
J B Naber, L Torralbo-Campo, T Hubert +1
We present our experimental investigation of an optical Raman transition between the magnetic clock states of Rb in an atom chip magnetic trap. The transfer of atomic popula…
Adsorbate dynamics on a silica-coated gold surface measured by Rydberg Stark spectroscopy
J. Naber, S. Machluf, L. Torralbo-Campo +4
Trapping a Rydberg atom close to a surface is an important step towards the realisation of many proposals of quantum information or hybrid quantum systems. One of the challenges in…
