Pi-phases in balanced fermionic superfluids on spin-dependent optical lattices
I. Zapata, B. Wunsch, N. T. Zinner +1
We study a balanced two-component system of ultracold fermions in one dimension with attractive interactions and subject to a spin-dependent optical lattice potential of opposite s…

Magnetic structure of an imbalanced Fermi gas in an optical lattice
B. Wunsch, L. Fritz, N. T. Zinner +2
We analyze the repulsive fermionic Hubbard model on square and cubic lattices with spin imbalance and in the presence of a parabolic confinement. We analyze the magnetic structure…
