Query: Comment on "Creating in-plane pseudomagnetic fields in excess of 1000 T
  by misoriented stacking in a graphene bilayer"   In a recent paper [Phys. Rev. B 89, 125418 (2014)], the authors argue that it
is possible to map the electronic properties of twisted bilayer graphene to
those of bilayer graphene in an in-plane magnetic field. However, their
description of the low-energy dynamics of twisted bilayer graphene is
restricted to the extended zone scheme and therefore neglects the effects of
the superperiodic structure. If the energy spectrum is studied in the supercell
Brillouin zone, we find that the comparison with an in-plane magnetic field
fails because (i) the energy spectra of the two situations exhibit different
symmetries and (ii) the low-energy spectra are very different.
