In the spirit of the holographic correspondence, which relates a gauge theory in D dimensions to a gravity theory in one dimension higher, we have developed a description of a 2+1 dimensional layer of graphene, starting from a N=2 supergravity theory in 3+1 dimensional anti de Sitter space. To this aim we have identified a particular asymptotic limit of the AdS4 supergravity to a locally AdS3 boundary, where it reproduces a D = 3 super-Chern Simons OSp(2|2) theory developed by J. Zanelli et al. in arXiv:1109.3944 and featuring unconventional local supersymmetry. This top-down approach (from higher to lower dimensions) is more predictive than the more common bottom-up one.
