Physics of Three-Dimensional Bosonic Topological Insulators: Surface-Deconfined Criticality and Quantized Magnetoelectric Effect

Abstract

Symmetry-protected topological states in systems where electronic interactions can be safely ignored have been theoretically predicted and experimentally confirmed. Theorists now investigate 3D systems of interacting bosons and find a new plethora of topological surface states with symmetry properties that are impossible to realize in a purely 2D electronic system.
