Antiferromagnetic topological insulators in cold atomic gases
Andrew M. Essin, Victor Gurarie
We propose a spin-dependent optical lattice potential that realizes a three-dimensional antiferromagnetic topological insulator in a gas of cold, two-state fermions such as alkalin…

Majorana spin liquids and projective realization of SU(2) spin symmetry
Gang Chen, Andrew Essin, Michael Hermele
We revisit the fermionic parton approach to S = 1/2 quantum spin liquids with SU(2) spin rotation symmetry, and the associated projective symmetry group (PSG) classification. We po…

Bulk-boundary correspondence of topological insulators from their Green's functions
Andrew M. Essin, Victor Gurarie
Topological insulators are noninteracting, gapped fermionic systems which have gapless boundary excitations. They are characterized by topological invariants, which can be written…
