A Microscopic Approach to Wolf Effect

Chapter

Abstract

It has been shown by Wolf1,2 that correlations between different parts of the source play an important role in determining the spectrum of the light emitted by the source. In particular, the frequency of the emitted light shows either a red shift or a blue shift as compared to its frequency when the source is assumed to be completely uncorrelated. Here, we present a microscopic model for the origin of this phenomenon.3 For simplicity, we assume that the source consists of a pair of two- level atoms interacting with each other via the dipole-dipole interaction. We also include the effects of the finite temperature of the source. For this microscopic model, we calculate the spectrum observed in the far zone. We show how the correlations between the atoms induced by the dipole-dipole interaction affects the red and blue frequency shifts in the spectrum.
