Hear the helium-4 quantum whistle!
Emile Hoskinson joined the Packard group in 1999 as a PhD student. He
was involved in the successful demonstration of the superfluid helium-3
gyroscope, a neutral fluid analog of the dc Superconducting Quantum
Interference Device (dc-SQUID). He went on to discover the helium-4 quantum
whistle, marking the first observation of Josephson oscillations in helium-4.
Soon after, he demonstrated a superfluid helium-4 dc-SQUID, which has a
significant advantage over the helium-3 version: it operates at 2 K, a
temperature 2000 times higher than for the helium-3 device. Compared to the
highly specialized refrigeration technology required to perform experiments
with superfluid helium-3, the helium-4 SQUID can be operated at low-cost,
without cryogenics expertise. This practical device is highly sensitive to
rotations and has the potential to become an important scientific probe.
