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…
