Michael Berry
OpenURL
Show Topic
The notion that a quantum system's wovefunction may not return to its original phase after its parameters cycle slowly around a circuit had many precursors—in polarized light, radio waves, molecules, matrices and curved surfaces.

The Physics of Metal Clusters

Marvin L. Cohen and Walter D. Knight
OpenURL
Show Topic
