0.75 atoms improve the clock signal of 10,000 atoms
I. Kruse, K. Lange, J. Peise +8
Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferomet…
Entanglement and extreme spin squeezing of unpolarized states
Giuseppe Vitagliano, Iagoba Apellaniz, Matthias Kleinmann +3
We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The cl…
Preparation of ultracold atom clouds at the shot noise level
Miroslav Gajdacz, Andrew J. Hilliard, Mick A. Kristensen +4
We prepare number stabilized ultracold clouds through the real-time analysis of non-destructive images and the application of feedback. In our experiments, the atom number ${N\sim1…
