(Anti-)de Sitter, Poincare, Super symmetries, and the two Dirac points of graphene

Popis výsledku v původním jazyce

We propose two different high-energy-theory correspondences with graphene (and related materials) scenarios, associated to grain boundaries, that are topological defects for which both Dirac points are necessary. The first correspondence points to a (3 + 1)-dimensional theory, with nonzero torsion, with spatiotemporal gauge group SO(3, 1), locally isomorphic to the Lorentz group in (3 + 1) dimensions, or to the de Sitter group in (2 + 1) dimensions. The other correspondence treats the two Dirac fields as an internal symmetry doublet, and it is linked here with unconventional supersymmetry with SU(2) internal symmetry. Our results are suggestive, rather than conclusive, and pave the way to the inclusion of grain boundaries in the emergent field theory picture associated with these materials, whereas disclinations and dislocations have been already well explored.
