Time reversal symmetry breaking of -orbital bosons in a one-dimensional optical lattice
Xiaopeng Li, Zixu Zhang, W. Vincent Liu
We study bosons loaded in a one-dimensional optical lattice of two-fold -orbital degeneracy at each site. Our numerical simulations find an anti-ferro-orbital p+ip, a ho…
Stripe, checkerboard, and liquid-crystal ordering from anisotropic p-orbital Fermi surfaces in optical lattices
Zixu Zhang, Xiaopeng Li, W. Vincent Liu
We study instabilities of single-species fermionic atoms in the p-orbital bands in two-dimensional optical lattices at noninteger filling against interactions. Charge density wave…
Finite temperature damping of collective modes of a BCS-BEC crossover superfluid
Zixu Zhang, W. Vincent Liu
A new mechanism is proposed to explain the puzzling damping of collective excitations, which was recently observed in the experiments of strongly interacting Fermi gases below the…
Modulated pair condensate of p-orbital ultracold fermions
Zixu Zhang, Hsiang-Hsuan Hung, Chiu Man Ho +2
We show that an interesting of pairing occurs for spin-imbalanced Fermi gases under a specific experimental condition---the spin up and spin down Fermi levels lying within the $p_x…
