Synthetic dimensions and spin-orbit coupling with an optical clock transition
L. F. Livi, G. Cappellini, M. Diem +8
We demonstrate a novel way of synthesizing spin-orbit interactions in ultracold quantum gases, based on a single-photon optical clock transition coupling two long-lived electronic…
Measuring absolute frequencies beyond the GPS limit via long-haul optical frequency dissemination
C. Clivati, G. Cappellini, L. Livi +12
Global Positioning System (GPS) dissemination of frequency standards is ubiquitous at present, providing the most widespread time and frequency reference for the majority of indust…
Beyond the fundamental noise limit in coherent optical fiber links
C. E. Calosso, E. Bertacco, D. Calonico +7
It is well known that temperature variations and acoustic noise affect ultrastable frequency dissemination along optical fiber. Active stabilization techniques are in general adopt…
Coherent optical frequency transfer at 5e-19 over a doubled 642 km fiber link
D. Calonico, E. K. Bertacco, C. E. Calosso +10
To significantly improve the frequency references used in radio-astronomy and precision measurements in atomic physics, we provide frequency dissemination through a 642 km coherent…
Frequency transfer via a two-way optical phase comparison on a multiplexed fiber network
Claudio Calosso, Elio K. Bertacco, Davide Calonico +6
We performed a two-way remote optical phase comparison on optical fiber. Two optical frequency signals were launched in opposite directions in an optical fiber and their phases wer…
