Abstract: (arXiv)
The physics of one dimensional optical superlattices with resonant ss-pp orbitals is reexamined in the language of appropriate Wannier functions. It is shown that details of the tight binding model realized in different optical potentials crucially depend on the proper determination of Wannier functions. We discuss the properties of a superlattice model which quasi resonantly couples ss and pp orbitals and show its relation with different tight binding models used in other works.
