Resonant wavepackets and shock waves in an atomtronic SQUID
Yi-Hsieh Wang, A. Kumar, F. Jendrzejewski +5
The fundamental dynamics of ultracold atomtronic devices are reflected in their phonon modes of excitation. We probe such a spectrum by applying a harmonically driven potential bar…
Minimally destructive, Doppler measurement of a quantized, superfluid flow
A. Kumar, N. Anderson, W. D. Phillips +3
The Doppler effect, the shift in the frequency of sound due to motion, is present in both classical gases and quantum superfluids. Here, we perform an in-situ, minimally destructiv…
Interferometric measurement of the current-phase relationship of a superfluid weak link
S. Eckel, F. Jendrzejewski, A. Kumar +2
Weak connections between superconductors or superfluids can differ from classical links due to quantum coherence, which allows flow without resistance. Transport properties through…
