Constructing superconductors by graphene Chern-Simons wormholes

We propose a new model which simulates the motion of free electrons in graphene by the evolution of strings on manifolds. In this model, molecules which constitute sheets of graphene are polygonal point-like structures which build (N + 1)-dimensional manifolds. By breaking the gravitational-analogue symmetry of graphene sheets, we show that two separated child sheets and a Chern-Simons bridge are produced giving rise to a wormhole. In this structure, free electrons are transmitted from one child sheet to the other producing superconductivity. An analogue between effective gravitons and Cooper pairs is found. In principle, this phenomenology provides the possibility to construct superconductor structures by using the analogue of cosmological models. (C) 2018 Elsevier Inc. All rights reserved.
