Photonic properties of bichromatic Optical Lattices — •Stefan Rist¹, Patrizia Vignolo², and Giovanna Morigi¹ — ¹Departament de Fisica, Universitat Autonoma de Barcelona — ²Institut Non-Linéaire de Nice, Université de Nice-Sophia Antipolis

We study theoretically the photonic spectrum of a bichromatic optical lattice, in the regime in which the atoms are well localized in the lattice sites and their dipolar transitions couple weakly to the probe light. The photonic spectrum is characterized as a function of the interparticle distance D inside the primitive Wigner-Seitz cell. Depending on D and on the atomic species composing the Wigner-Seitz cell, two or more photonic bandgaps can be found. We then determine the dynamics, when the atoms couple to the standing-wave mode of a Fabry-Perot cavity, and study the cavity transmission spectrum in the strong coupling regime.
