Scientists discover zero-sound mode oscillations in super-chilled helium. Scientists 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 will interest researchers looking at electronic systems, since high-temperature superconductivity could result from this type of density fluctuation.
