Superfluids are notable for their unique properties and behaviors arising from the quantum interactions of the particles that make them up. Despite their quantum quirks, superfluids sometimes still behave in mundane ways. A new experiment captured images of two superfluids coming together and revealed that despite their quantum nature, they can still behave in ways that resemble the ripples and mushroom clouds seen in normal fluids.
A new experiment let JQI researchers get an unprecedented look at the currents hiding in a superfluid. The technique they developed allows them to measure the fluid velocity at specific locations in a superfluid, opening new opportunities to investigate the dynamics of superfluids, including how they experience turbulence.
