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…
