Abstract

This post-doctoral project aims at determining how the new spectral lines translates in terms of joint emission of photons, with cascades of real and virtual ('leapfrog') processes. While correlations between photons of different colours have been demonstrated for single emitters (usingcold atoms and quantum dots), the interaction-induced correlations remain to be explored. Thepost-doctoral researcher will focus on correlations and entanglement of photons with different colors, by monitoring higher-order photon-photon correlations. (AU)
