Low frequency elastic measurements on solid He in Vycor using a torsional oscillator
A. D. Fefferman, J. R. Beamish, A. Haziot +1
Torsional oscillator experiments involving solid He confined in the nanoscale pores of Vycor glass showed anomalous frequency changes at temperatures below 200 mK. These were…

Critical dislocation speed in helium-4 crystals
Ariel Haziot, Andrew Fefferman, Fabien Souris +3
Our experiments show that in He crystals, the binding of He impurities to dislocations does not necessarily imply their pinning. Indeed, in these crystals, there are two di…

The giant plasticity of a quantum crystal
Ariel Haziot, Xavier Rojas, Andrew D. Fefferman +2
When submitted to large stresses at high temperature, usual crystals may irreversibly deform. This phenomenon is known as plasticity and it is due to the motion of crystal defects…
