Quantum whistling in superfluid helium-4
Article Abstract:
Macroscopic quantum systems are made to undergo oscillations in superfluid helium-4 [(super 4) He] by pushing it through an array of nanometer-sized apertures. It is found that [(super 4) He] in an array of small apertures behaves quantum coherently, oscillating at the Josephson frequency.

Probable heat capacity signature of the supersolid transition
Article Abstract:
The finding of a heat capacity peak that coincides with the onset of mass decoupling is reported. This confirms the existence of a genuine transition between the normal solid and supersolid phases of [super 4]He.
