A double-well atom trap for fluorescence detection at the Heisenberg limit
Ion Stroescu, David B. Hume, Markus K. Oberthaler
We experimentally demonstrate an atom number detector capable of simultaneous detection of two mesoscopic ensembles with single-atom resolution. Such a sensitivity is a prerequisit…
Nonlinear dressed states at the miscibility-immiscibility threshold
E. Nicklas, W. Muessel, H. Strobel +2
The dynamical evolution of spatial patterns in a complex system can reveal the underlying structure and stability of stationary states. As a model system we employ a two-component…
Scalable Spin Squeezing for Quantum-Enhanced Magnetometry with Bose-Einstein Condensates
W. Muessel, H. Strobel, D. Linnemann +2
A major challenge in quantum metrology is the generation of entangled states with macroscopic atom number. Here, we demonstrate experimentally that atomic squeezing generated via n…
