Neutrons uncover new density waves in fermion liquids - a publication in Nature today

Scientists discover zero-sound mode oscillations in super-chilled helium.

Scientists working at the Institut Laue-Langevin have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered a new type of very short wave-length density wave. The team believe their discovery, published today in Nature, will interest researchers looking at electronic systems, since high-temperature superconductivity could result from this type of density fluctuation.
