摘要
In this work we use the fermionic structure of the low-energy excitations of graphene (a monolayer of carbon atoms) to construct a new supersymmetric graphene field theory. In the current literature, concerning the inhomogeneities between neighbor carbon atoms, Jackiw et al. constructed a useful chiral Abelian gauge theory. Other supersymmetries in a theory for graphene were analyzed at the level of supersymmetric quantum mechanics. In our formulation, all these gauge theories constructed before are shown precisely to be sectors of a wider and richer planar gauge theory given here. A detailed analysis of the spectrum of this graphene field theory is also carried out.
