Low temperature acoustic properties of amorphous silica and the Tunneling Model
EunJoo Thompson, G. Lawes, J. M. Parpia +1
Internal friction and speed of sound of a-SiO(2) was measured above 6 mK using a torsional oscillator at 90 kHz, controlling for thermal decoupling, non-linear effects, and clampin…

Universal Behaviour of the Superfluid Fraction and Tc of He-3 in 99.5% Open Aerogel
G. Lawes, S. C. J. Kingsley, N. Mulders +1
We have investigated the superfluid transition of He-3 in a 99.5% porosity silica aerogel. This very dilute sample shows behaviour intermediary between bulk He-3 and He-3 confined…
