Spectral evolution of two-photon emission in microresonators
Francesca Famà, Stefano Dello Russo, Stefano Giaccari +14
High-Q silicon nitride microresonators are versatile sources for generating photon pairs via four-wave mixing. We investigate the spectral coherence of this process, tracking the t…

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…
