Acoustic Spectroscopy of Superfluid 3He in Aerogel
N. Mulders Department of Physics and Astronomy, University of Delaware, 223 Sharp Laboratory, Newark, Delaware 19716 (Received 21 December 1998) Liquid 3He in 98%-porous aerogel simultaneously possesses properties of a disordered p-wave superfluid and an elastic solid. We have observed two sound modes of superfluid 3He in aerogel. The first (fast) sound is a compression wave, and the second (sl...
متن کاملSuperfluid transition in superfluid 3He in radially compressed aerogel
The Spin Supercurrent and Bose-Einstein condensation of magnons similar to an atomic BEC was observed in 1984 in superfluid He-B. Recently we discovered 2 new types of BEC in superfluid He in deformed aerogel. The orbital part of the wave function orients along the deformation and changes the magnon-magnon interaction. In some cases it forms a magnon trap. We can do it for He-A by uniaxially co...
متن کاملDissipation mechanisms near the superfluid 3He transition in aerogel.
We have investigated the dissipation (Q-1) using the torsion pendulum technique for pure 3He and 3He-4He mixtures in silica aerogel near the 3He superfluid transition (T(c)) in aerogel. With pure 3He the Q-1 decreases at the onset of superfluidity. When phase separated 3He-4He mixtures are introduced into the aerogel, the Q-1 does not decrease as rapidly and eventually increases for the highest...
متن کاملScaling Results for Superfluid 3He in 98% Open Aerogel
We present experimental observations of the suppressed superfluid transition temperature, Tca, superfluid fraction, ρs/ρ and Leggett frequency of 3He-B in aerogel, ΩBa. We determine Tca from mass decoupling and the vanishing of the frequency shift away from the Larmor frequency in our different samples and different laboratories. We find that the suppressed transition temperature for 3He in aer...
متن کاملObservation of a new superfluid phase for 3He embedded in nematically ordered aerogel
In bulk superfluid 3He at zero magnetic field, two phases emerge with the B-phase stable everywhere except at high pressures and temperatures, where the A-phase is favoured. Aerogels with nanostructure smaller than the superfluid coherence length are the only means to introduce disorder into the superfluid. Here we use a torsion pendulum to study 3He confined in an extremely anisotropic, nemati...
