In this work, it is shown that an array of atoms inside an optical cavity can act as a controllable quantum non-linear optical medium. Here, the quantum properties of the generated light can be tuned by changing the interparticle distance with respect to cavity mode wavelength.
We characterize the quantum nature of the emitted light by the lattice as a function of the interparticle distance and the coupling amplitude between the lattice and the electromagnetic field and we discuss in which regime for the parameters the system can act as a single photon source.
