wave packet [′wāv ‚pak·ət] (physics) In wave phenomena, a superposition of waves of differing lengths, so phased that the resultant amplitude is negligibly small except in a limited portion of space whose dimensions are the dimensions of the packet. Also known as packet. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

| In the recent atomic experiment, the researchers make one cold beryllium atom vibrate harmonically, producing what they call a superposition of two "coherent-state wave packets. Over time, each of these circulating wave packets spreads out and ultimately evolves into a pair of smaller wave packets on opposite sides of the orbit. By achieving such control over electron wave packets, researchers may gain insights into how the quantum mechanics of the microscopic realm meshes with the classical mechanics of everyday objects. |
