Levy flight and Anderson localization of polar molecules — •Xiaolong Deng1, Boris Altshuler2, Gora Shlyapnikov3, and Luis Santos1 — 1ITP, Uni. Hannover — 2Physics Dept, Columbia Uni., USA — 3LPTMS, CNRS, France
Rotational excitations in polar molecules in deep optical lattices realize a quantum percolation model with long-range hops, whose properties depend on both lattice filling and dimensionality. Using spectral and multi-fractal analysis, we show that whereas in 1D and 2D all eigenstates are localized, while in 3D all are delocalized.
