Probing the Vacuum Induced Coherence in a $\Lambda$-system

Quantum Physics 2007-05-23 v1

Abstract

We propose a simple test to demonstrate and detect the presence of vacuum inducde coherence in a Λ\Lambda-system. We show that the probe field absorption is modulated due to the presence of such a coherence which is unobservable in fluorescence. We present analytical and numerical results for the modulated absorption, the cosine and sine components of which display different types of behavior.
