Absolute frequency measurement of rubidium 5S-6P transitions
Conny Glaser, Florian Karlewski, Jens Grimmel +4
We report on measurements on the 5S-6P rubidium transition frequencies for rubidium isotopes with an absolute uncertainty of better than \SI{450}{kHz} for the 5S 6P$_…
All-optical measurement of Rydberg state lifetimes
Markus Mack, Jens Grimmel, Florian Karlewski +3
We have developed an all-optical method for measuring the lifetimes of and Rydberg states and demonstrate its capabilities with measurements on a dilute cloud of ultrac…
Sensitivity of ultracold atoms to quantized flux in a superconducting ring
P. Weiss, M. Knufinke, S. Bernon +7
We report on the magnetic trapping of an ultracold ensemble of Rb atoms close to a superconducting ring prepared in different states of quantized magnetic flux. The niobium…
Controlling the magnetic field sensitivity of atomic clock states by microwave dressing
L. Sárkány, P. Weiss, H. Hattermann +1
We demonstrate control of the differential Zeeman shift between clock states of ultracold rubidium atoms by means of non-resonant microwave dressing. Using the dc-field dependence…
Trapping of ultra cold atoms in a 3He/4He dilution refrigerator
F. Jessen, M. Knufinke, S. C. Bell +13
We describe the preparation of ultra cold atomic clouds in a dilution refrigerator. The closed cycle 3He/4He cryostat was custom made to provide optical access for laser cooling, o…
Manipulation and coherence of ultra-cold atoms on a superconducting atom chip
S. Bernon, H. Hattermann, D. Bothner +8
The coherence of quantum systems is crucial to quantum information processing. While it has been demonstrated that superconducting qubits can process quantum information at microel…
