Spontaneous symmetry breaking in spinor Bose-Einstein condensates
M. Scherer, B. Lücke, O. Topic +6
We present an analytical model for the theoretical analysis of spin dynamics and spontaneous symmetry breaking in a spinor Bose-Einstein condensate (BEC). This allows for an excell…
Spontaneous breaking of spatial and spin symmetry in spinor condensates
M. Scherer, B. Lücke, G. Gebreyesus +6
Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric…
Parametric amplification of matter waves in dipolar spinor Bose-Einstein condensates
F. Deuretzbacher, G. Gebreyesus, O. Topic +6
Spin-changing collisions may lead under proper conditions to the parametric amplification of matter waves in spinor Bose-Einstein condensates. Magnetic dipole-dipole interactions,…
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…
