Query: Subwavelength vacuum lattices and atom-atom interactions in photonic
  crystals   We propose the use of photonic crystal structures to design subwavelength
optical lattices in two dimensions for ultracold atoms by using both Guided
Modes and Casimir-Polder forces. We further show how to use Guided Modes for
photon-induced large and strongly long-range interactions between trapped
atoms. Finally, we analyze the prospects of this scheme to implement spin
models for quantum simulation
