Measurement and control of the interaction frequency shift in bosonic optical lattice clocks
J. P. Salvatierra, M. Barbiero, G. Bertaina +3
We report precise measurements of inter-level interactions in a bosonic optical lattice clock based on Sr atoms. We observe a nonlinear density dependence of the clock shift…

Analysis of spin-squeezing generation in cavity-coupled atomic ensembles with continuous measurements
A. Caprotti, M. Barbiero, M. G. Tarallo +2
We analyze the generation of spin-squeezed states via coupling of three-level atoms to an optical cavity and continuous quantum measurement of the transmitted cavity field in order…
