SUMMARY:Exactly Solvable Lattice Hamiltonians and Gravitational Anomalies
DESCRIPTION:Abstract: We construct infinitely many new exactly solvable local commuting projector lattice Hamiltonian models for general bosonic beyond group cohomology invertible topological phases of order two and four in any spacetime dimensions\, whose boundaries are characterized by gravitational anomalies. Examples include the beyond group cohomology invertible phase “w2w3” in (4+1)D that has an anomalous boundary topological order with fermionic particle and fermionic loop excitations that have mutual statistics. Finally\, we will demonstrate a few examples of fermionic loop excitations.
