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…
Self-heterodyne detection of the {\it in-situ} phase of an atomic-SQUID
Ranchu Mathew, Avinash Kumar, Stephen Eckel +4
We present theoretical and experimental analysis of an interferometric measurement of the {\it in-situ} phase drop across and current flow through a rotating barrier in a toroidal…
Contact resistance and phase slips in mesoscopic superfluid atom transport
S. Eckel, Jeffrey G. Lee, F. Jendrzejewski +3
We have experimentally measured transport of superfluid, bosonic atoms in a mesoscopic system: a small channel connecting two large reservoirs. Starting far from equilibrium (super…
