comment Graphene and Klein bottle?
In ordinary insulator the effective Hamiltonian has a topology of a torus, but in HgTe quantum well the effective Hamiltonian is topologically equivalent to a real projective plane (non-orientable manifold) see arxiv.org/abs/1102.3282.

comment What does it mean to say “Gravity is the weakest of the forces”?
No, is not about the difference of coupling constants, is about quadratic divergence of Higgs mass correction (first order radiative correction). I will find a question about it. This area of comments is not appropriate for a more detailed answer.

comment What does it mean to say “Gravity is the weakest of the forces”?
Actually the Hierarchy problem is about the radiative corrections in the Higgs propagator. The large discrepancy of coupling constants is not a real problem.
