Uniform pseudomagnetic fields in graphene: corrections due to lattice   deformations
  Very recently, the standard description of electrons in strained graphene has been completed by the explicit inclusion of the lattice deformation. Here, the effect of these lattice corrections is taken into account to find the mechanical deformations that generate a uniform pseudomagnetic field inside strained graphene. The main difference when compared with previous proposals in a rectangular geometry, is the need to stretch both zigzag and armchair edges.
