Experimentally the gapped (insulating) state has never been observed. Theorists would like to provide information on how a gap could be produced. We study the effect on the critical coupling of straining a graphene lattice. We work with a low energy effective theory obtained by considering a tight-binding Hamiltonian expanded around the Dirac points in momentum space.engQuantum Electrodynamics, Graphene, Computational Modellingmaster thesis
