Journal ArticleDOI
Magnetoelectric polarizability and axion electrodynamics in crystalline insulators
TL;DR: The orbital motion of electrons in a three-dimensional solid can generate a pseudoscalar magnetoelectric coupling theta, a fact that can be generalized to the many-particle wave function and defines the 3D topological insulator in terms of a topological ground-state response function.
Journal ArticleDOI
Antiferromagnetic topological insulators
TL;DR: In this article, the authors consider antiferromagnets breaking both time-reversal and a primitive-lattice translational symmetry of a crystal but preserving the combination $S=\ensuremath{\Theta}{T} 1/2}.

Journal ArticleDOI
Bulk-boundary correspondence of topological insulators from their respective Green's functions
Andrew M. Essin,Victor Gurarie +1 more
TL;DR: In this article, the existence of edge states directly follows from the presence of the topological invariant written in terms of the Green's functions, for all ten classes of topological insulators in all spatial dimensions.
Journal ArticleDOI
Classifying fractionalization: Symmetry classification of gapped Z 2 spin liquids in two dimensions
Andrew M. Essin,Michael Hermele +1 more
TL;DR: In this paper, the fractionalization class of each anyon is an equivalence class of projective representations of the symmetry group, corresponding to elements of the cohomology group.
