Double occupancy as a probe of the Mott transition for fermions in one-dimensional optical lattices

Two contributed talks given at SCES 2011, Cambridge (follow this link for the official abstract) and at the annual meeting of the UK Cold Atoms/Condensed Matter interface network. The slides below were used at Nottingham (they are a slightly improved version of the slides used at Cambridge). They cover the work in preprint arXiv:1107.4349 (see also our earlier post on that preprint).
