comment can gapped systems have gravitational anomalies?
$E_8$ state has non-trivial topological order, and its boundary has a perturbative gravitational anomaly.

comment Is the Standard Model consistent (UV complete)?
I wonder the non-perturbative effects and the inconsistencies may show up near electric-weak phase transition, ie around T=200GeV.

The modified Standard Model with 16 Weyl fermions per family is a low energy effective theory of SO(10) GUT. The SO(10) GUT is consistent (ie UV complete) -> The modified Standard Model with 16 Weyl fermions per family is consistent (ie UV complete)

comment What does it mean for a Hamiltonian or system to be gapped or gapless?
Yes, the reasonable sequence should be ensuring the number of lattice sites to be even.

comment What does it mean for a Hamiltonian or system to be gapped or gapless?
Yes. Haah's cubic code is such an example. And one can easily construct many other examples by stack 2D topologically ordered states to form a 3D gapped state.
