An efficient high-current circuit for fast radio-frequency spectroscopy in cold atomic gases
F. Scazza, G. Del Pace, L. Pieri +3
We design and implement a low-impedance, high-current radio-frequency (RF) circuit, enabling fast coherent coupling between magnetic levels in cold alkali atomic samples. It is bas…

Shapiro steps in strongly-interacting Fermi gases
Giulia Del Pace, Diego Hernández-Rajkov, Vijay Pal Singh +7
We report the observation of Shapiro steps in a periodically driven Josephson junction between strongly-interacting Fermi superfluids of ultracold atoms. We observe quantized plate…
