Fermi nesting between atomic wires with strong spin-orbit coupling

Tegenkamp, Christoph; Lükermann, Daniel; Pfnür, Herbert; Slomski, B.; Landolt, G.; Dil, J.H. (College Park, MD : American Physical Society, 2012)

The mutual interplay between superlattice structures, band filling factors, and spin-orbit coupling results in a highly correlated electronic spin and charge state found for an array of atomic Pb wires grown on Si(557). ...
Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field

Greschner, Sebastian; Piraud, M.; Heidrich-Meisner, F.; McCulloch, I.P.; Schollwöck, U.; Vekua, T. (College Park, MD : American Physical Society, 2016)

We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting states, including Meissner phases, vortex ...
Vortex-Hole Duality: A Unified Picture of Weak- and Strong-Coupling Regimes of Bosonic Ladders with Flux

Greschner, Sebastian; Vekua, T. (College Park, MD : American Physical Society, 2017)

Two-leg bosonic ladders with flux harbor a remarkable vortex-hole duality between the weak-coupling vortex lattice superfluids and strong-coupling charge-density-wave crystals. The strong-coupling crystalline states, which ...
