Query: Exactly Solvable Models for Symmetry-Enriched Topological Phases   We construct fixed-point wave functions and exactly solvable
commuting-projector Hamiltonians for a large class of bosonic symmetry-enriched
topological (SET) phases, based on the concept of equivalent classes of
symmetric local unitary transformations. We argue that for onsite unitary
symmetries, our construction realizes all SETs free of anomaly, as long as the
underlying topological order itself can be realized with a commuting-projector
Hamiltonian. We further extend the construction to anti-unitary symmetries
(e.g. time-reversal symmetry), mirror-reflection symmetries, and to anomalous
SETs on the surface of three-dimensional symmetry-protected topological phases.
Mathematically, our construction naturally leads to a generalization of group
extensions of unitary fusion categories to anti-unitary symmetries.
