Electrons in boxes: probing artificial atoms to stretch quantum physics.

From: Science News | Date: April 11, 1998| Author: Peterson, Ivars | Copyright information

Researchers are using artificial atoms called quantum dots to study quantum mechanics and the effects of interactions involving electrons. Quantum dot experiments discussed at the Mar 1998 American Physical Society meeting are reviewed.

Weird things happen when particles are confined to tiny boxes.

An atom, for example, can be pictured as a spherical container for electrons. The attractive electrical force between the negatively charged electrons and the atom's posit...
