Intensity correlation as a means of manifesting coherent atomic excitation

  • M. P. Silverman
Article

Summary

The excitation of atoms into a coherent linear superposition of states may not always be revealed by measurement of the spontaneous-emission intensity at a single detector. Correlation of the intensity at two detectors, however, can under specified circumstances reveal this coherent excitation.

Riassunto

L'eccitazione di atomi in una coerente sovrapposizione lineare di stati non può essere sempre rivelata dalla misurazione dell'intensità di emissione spontanea. La correlazione dell'intensità nei due rivelatori, comunque, può in alcune circostanze specifiche rivelare questa eccitazione coerente.
