▎ 摘  要

Supersymmetry is expected to exist in nature at high energies, but must be spontaneously broken at ordinary energy scales. The required energy scale in elementary particle physics is currently inaccessible, but condensed matter could furnish low energy realizations of supersymmetry. In graphene, electrons behave as 'relativistic' massless fermions in 1 + 2 dimensions. Here we propose phenomenologically, assuming that some microscopic parameters can be fine-tuned in graphene, the existence of a supersymmetric Wess-Zumino phase. The supersymmetry breaking leads to a superconductor phase, described by a relativistic Ginzburg-Landau phenomenology. (C) 2013 Elsevier B.V. All rights reserved.
