Electron shelving in a lattice system

Abstract

It is shown that the 'electron shelving scheme' used in experiments on quantum jumps in single atoms may serve as an effective tool for investigation of electron dynamics in spatially distributed quantum systems. The statistics of long interruptions in resonance fluorescence of a single impurity incorporated into a model lattice system is considered. It is shown that the statistics reflects the character of the electron motion on the lattice in the vicinity of the impurity. Both the cases of coherent and incoherent electron dynamics are discussed.
