Discovery of the Acoustic Faraday Effect in Superfluid 3He-B

open access: yes, 1999
We report the discovery of the acoustic Faraday effect in superfluid 3He-B. The observation of this effect provides the first direct evidence for propagating transverse acoustic waves in liquid 3He, a mode first predicted by Landau in 1957.

Constant-pressure sound waves in non-Hermitian disordered media

open access: yes, 2018
When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions in the free propagation of a wave is a challenging task with many applications in a number of different ...
