Double occupancy as a universal probe for antiferromagnetic correlations and entropy in cold fermions on optical lattices

E. V. Gorelik, T. Paiva, R. Scalettar +2

We verify signatures of antiferromagnetic (AF) correlations in the double occupancy D [Gorelik et al., PRL 105, 065301 (2010)] and study their dimensional dependence using direct q…
