Phys. Rev. A 76, 023818 (2007) [5 pages]Entangled light via nonlinear vacuum-multiparticle interactionsReceived 20 June 2007; published 20 August 2007 We investigate the generation of a strongly entangled electromagnetic field through laser pumping a collection of N two-level atoms in a two-mode optical resonator. The vacuum-multiparticle interactions enhance the coupling of the atomic sample to the cavity modes facilitating the creation of entangled photons at higher frequencies. In the dispersive atom-cavity limit, one can obtain a steady-state output field consisting of tens of such photons per mode. © 2007 The American Physical Society URL:
