Title

Probing the classical/quantal boundary using the Stark effect

Abstract

"The boundary between classical physics and quantum physics is examined using the Stark effect on sodium atoms in a constant electric field. Coherent states composed of linear superpositions of the hydrogenic stationary states are created by applying a low amplitude, ~5 V/cm, nanosecond electric field pulse. The pulse periodically drives the atoms to a realm where many stationary states lie within a very narrow energy range. These coherent superpositions exhibit localized electronic probability densities and therefore qualify as wave packets, time-dependent states for which constructive and destructive interference leads to a localized, moving probability density. Using a cw laser these wave packet states are excited and their attributes are probed in the frequency domain rather than the time domain. Computer simulations are used to show how coherent linear combinations of hydrogenic basis states emulate the orbital motion of a classical particle"--Abstract, leaf iii.
