Emile Michael Hoskinson


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.

Emile completed a BSc in physics at the University of British Columbia in 1999. It was here he was first introduced to the field of low-temperature physics as part of his undergraduate thesis project in the high-Tc superconductivity lab of Walter Hardy and Doug Bonn.


He completed his PhD at Berkeley in Dec 2005 and is currently a post-doctoral research scientist at the CRTBT in Grenoble, France, studying quantum behavior in superconducting Josephson junction circuits.
