The -orbital counterpart of graphene: cold atoms in the honeycomb optical lattice
Congjun Wu, S. Das Sarma
We study the ground state properties of the interacting spinless fermions in the -orbital bands in the two dimensional honeycomb optical lattice, which exhibit different n…

Flat bands and Wigner crystallization in the honeycomb optical lattice
Congjun Wu, Doron Bergman, Leon Balents +1
We study the ground states of cold atoms in the tight-binding bands built from p-orbitals on a two dimensional honeycomb optical lattice. The band structure includes two completely…

Order by disorder and spiral spin liquid in frustrated diamond lattice antiferromagnets
Doron Bergman, Jason Alicea, Emanuel Gull +2
Frustration refers to competition between different interactions that cannot be simultaneously satisfied, a familiar feature in many magnetic solids. Strong frustration results in…
