Parametric amplification of vacuum fluctuations in a spinor condensate
C. Klempt, O. Topic, G. Gebreyesus +6
Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplificatio…
Multi-resonant spinor dynamics in a Bose-Einstein condensate
C. Klempt, O. Topic, G. Gebreyesus +6
We analyze the spinor dynamics of a Rb-87 F=2 condensate initially prepared in the m_F=0 Zeeman sublevel. We show that this dynamics, characterized by the creation of correlated at…
Radio frequency association of heteronuclear Feshbach molecules
C. Klempt, T. Henninger, O. Topic +5
We present a detailed analysis of the production efficiency of weakly bound heteronuclear KRb-Feshbach molecules using radio frequency association in a harmonic trap. The efficienc…
Transport of a quantum degenerate heteronuclear Bose-Fermi mixture in a harmonic trap
C. Klempt, T. Henninger, O. Topic +4
We report on the transport of mixed quantum degenerate gases of bosonic 87Rb and fermionic 40K in a harmonic potential provided by a modified QUIC trap. The samples are transported…
KRb Feshbach Resonances: Modeling the interatomic potential
C. Klempt, T. Henninger, O. Topic +4
We have observed 28 heteronuclear Feshbach resonances in 10 spin combinations of the hyperfine ground states of a 40K 87Rb mixture. The measurements were performed by observing the…
UV light-induced atom desorption for large rubidium and potassium magneto-optical traps
C. Klempt, T. van Zoest, T. Henninger +4
We show that light-induced atom desorption (LIAD) can be used as a flexible atomic source for large Rb-87 and K-40 magneto-optical traps. The use of LIAD at short wavelengths allow…
