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…
Twin matter waves for interferometry beyond the classical limit
Bernd Lücke, Manuel Scherer, Jens Kruse +10
Interferometers with atomic ensembles constitute an integral part of modern precision metrology. However, these interferometers are fundamentally restricted by the shot noise limit…
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…
