Fermi-Bose mixture in mixed dimensions
M. A. Caracanhas, F. Schreck, C. Morais Smith
One of the challenging goals in the studies of many-body physics with ultracold atoms is the creation of a topological superfluid for identical fermions in two dim…
Topological Varma superfluid in optical lattices
M. Di Liberto, A. Hemmerich, C. Morais Smith
Topological states of matter are peculiar quantum phases showing different edge and bulk transport properties connected by the bulk-boundary correspondence. While non-interacting f…
Interaction-induced chiral p_x \pm i p_y superfluid order of bosons in an optical lattice
M. Ölschläger, T. Kock, G. Wirth +3
The study of superconductivity with unconventional order is complicated in condensed matter systems by their extensive complexity. Optical lattices with their exceptional precision…
Spin-charge-density wave in a squircle-like Fermi surface for ultracold atoms
D. Makogon, I. B. Spielman, C. Morais Smith
We derive and discuss an experimentally realistic model describing ultracold atoms in an optical lattice including a commensurate, but staggered, Zeeman field. The resulting band s…
Strongly Interacting Two-Dimensional Dirac Fermions
Lih-King Lim, Achilleas Lazarides, Andreas Hemmerich +1
We show how strongly interacting two-dimensional Dirac fermions can be realized with ultracold atoms in a two-dimensional optical square lattice with an experimentally realistic, i…
Staggered-Vortex Superfluid of Ultracold Bosons in an Optical Lattice
Lih-King Lim, C. Morais Smith, Andreas Hemmerich
We show that the dynamics of cold bosonic atoms in a two-dimensional square optical lattice produced by a bichromatic light-shift potential is described by a Bose-Hubbard model wit…
