Vortex-Line Condensation in Three Dimensions: A Physical Mechanism for Bosonic Topological Insulators

Bosonic topological insulators (BTIs) in three dimensions are symmetry-protected topological phases protected by time-reversal and boson number conservation symmetries. BTIs in three dimensions were first proposed and classified by the group cohomology theory, which suggests two distinct root states...
