Magnets get their act together

Article Abstract:

Continuing efforts to explain the properties of macroscopic magnets in terms of quantum mechanics may well revolutionize both theoretical physics and the technology based on it. The essence of the new research is that macroscopic magnets should exhibit quantum tunneling or interference when two different magnetic states interact. This renewed interest in quantum magnetism is bringing together such seemingly incongruous lines of research as the protein molecules from equine spleen, Richard Feynman's research on quantum computers and Schrodinger's cat paradox.

The geometric phase

Article Abstract:

A new perspective on quantum mechanics was gained with confirmation that geometric phases can arise in developing quantum systems. These phases constitute the systems' memory in the sense of allowing a system to revert to an earlier physical condition. Experiments with nuclear magnetic resonance, spin-polarized neutrons and sodium chlorate crystals have all verified the existence of geometric phases in quantum systems.
