Active SU(1,1) atom interferometry
D. Linnemann, J. Schulz, W. Muessel +5
Active interferometers use amplifying elements for beam splitting and recombination. We experimentally implement such a device by using spin exchange in a Bose-Einstein condensate.…

Fisher Information and entanglement of non-Gaussian spin states
Helmut Strobel, Wolfgang Muessel, Daniel Linnemann +5
Entanglement is the key quantum resource for improving measurement sensitivity beyond classical limits. However, the production of entanglement in mesoscopic atomic systems has bee…

Twist-and-Turn Spin Squeezing in Bose-Einstein Condensates
W. Muessel, H. Strobel, D. Linnemann +3
We experimentally demonstrate an alternative method for the dynamic generation of atomic spin squeezing, building on the interplay between linear coupling and nonlinear phase evolu…
