Tunable nanomagnetism in moderately cold fermions on optical lattices
E. V. Gorelik, N. Blümer
Localized defects, unavoidable in real solids, may be simulated in (generically defect-free) cold-atom systems, e.g., via modifications of the optical lattice. We study the Hubbard…
Discriminating antiferromagnetic signatures in ultracold fermions by tunable geometric frustration
Chia-Chen Chang, Richard T. Scalettar, Elena V. Gorelik +1
Recently, it has become possible to tune optical lattices continuously between square and triangular geometries. We compute thermodynamics and spin correlations in the correspondin…
Mott transitions in the half-filled SU(2M) symmetric Hubbard model
N. Blümer, E. Gorelik
The Hubbard model with large orbital degeneracy has recently gained relevance in the context of ultracold earth alkali like atoms. We compute its static properties in the SU(2M) sy…
Momentum-dependent pseudogaps in the half-filled two-dimensional Hubbard model
D. Rost, E. V. Gorelik, F. Assaad +1
We compute unbiased spectral functions of the two-dimensional Hubbard model by extrapolating Green functions, obtained from determinantal quantum Monte Carlo simulations, to the th…
Universal probes for antiferromagnetic correlations and entropy in cold fermions on optical lattices
E. V. Gorelik, D. Rost, T. Paiva +3
We determine antiferromagnetic (AF) signatures in the half-filled Hubbard model at strong coupling on a cubic lattice and in lower dimensions. Upon cooling, the transition from the…
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…
