High-pressure geophysics and materials

Spin waves, which are collective periodic variations of the magnetization vector, have been found in both sodium and potassium. This is the first observation of genuine many-body effects in a solid-state plasma, and it confirms the collective Fermi-liquid model first proposed by Lev Landau ten years ago.
