Transverse acoustic spectroscopy of Superfluid $^{3}$He in compressed aerogel.
ORAL
Abstract
In light of the recent developments on the A-B transition in superfluid $^{3}$He in aerogel and the effect of anisotropic scattering$^{2}$, we have designed an experiment to perform transverse acoustic impedance measurements on compressed aerogel. We investigate the effect of global anisotropy on the phase transition, generated by introducing uniaxial compression of 5 {\%} on the aerogel. We report our preliminary results together with the measurements on the uncompressed aerogel.
