Minimally destructive, Doppler measurement of a quantized flow in a ring-shaped Bose–Einstein condensate

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 destructive measurement, of the persistent current in a ring-shaped, superfluid Bose–Einstein condensate using the Doppler effect...
