Directed spontaneous emission from an extended ensemble of N atoms: timing is everything

A collection of N static atoms is fixed in a crystal at a low temperature and prepared by a pulse of incident radiation of wave vector k ->(0). The N atoms are well described by an entangled Dicke-like state, in which each atom carries a characteristic phase factor exp(ik ->(0)center dot r -&g...
