Discovery of the acoustic Faraday effect in superfluid (super3)He-B
Article Abstract:
Acoustic waves are useful in studying the structure of matter. Compression and shear waves occur in solids, but normal liquids do not support shear forces. Landau predicted in 1957 that the quantum-liquid phase of helium-3 could support transverse sound waves at low temperatures. The existence of transverse sound waves in superfluid (super3)He-B is experimentally confirmed, through observations of the rotation of their polarization in the presence of a magnetic field, the acoustic analogue of the magneto-optic Faraday effect.

Vortex lattice melts like ice
Article Abstract:
The results of a study on type II superconductors in a magnetic field shows that the magnetic vortex filaments in a high-temperature superconducting compound melt following first-order phase transition. The results also showed that the vortex liquid expands upon freezing in the same way that water expands when transformed into ice. The study demonstrates that matter composed of flexible directed lines exhibits different behavior from assemblies of point-like molecules or atoms.
