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$_…
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…
Parametric amplification of the mechanical vibrations of a suspended nanowire by magnetic coupling to a Bose-Einstein condensate
Z. Darázs, Z. Kurucz, O. Kálmán +3
We consider the possibility of parametric amplification of a mechanical vibration mode of a nanowire due to its interaction with a Bose-Einstein condensate (BEC) of ultracold atoms…
Cold atoms near superconductors: Atomic spin coherence beyond the Johnson noise limit
B. Kasch, H. Hattermann, D. Cano +6
We report on the measurement of atomic spin coherence near the surface of a superconducting niobium wire. As compared to normal conducting metal surfaces, the atomic spin coherence…
Rubidium Spectroscopy at 778-780 nm with a Distributed Feedback Laser Diode
S. Kraft, A. Deninger, Ch. Truck +3
We have performed high resolution spectroscopy of rubidium with a single mode continuous wave distributed feedback (DFB) laser diode. The saturation spectrum of the D_2-line of 85R…
Microelectromagnets for Trapping and Manipulating Ultracold Atomic Quantum Gases
J. Fortagh, H. Ott, G. Schlotterbeck +3
We describe the production and characterization of microelectromagnets made for trapping and manipulating atomic ensembles. The devices consist of 7 fabricated parallel copper cond…
