Strain-induced pseudomagnetic and scalar fields in symmetry-enforced Dirac nodes
arXiv:1707.02781 · doi:10.1016/j.jmmm.2017.12.056
Abstract
It is known that Dirac nodes can be present at high-symmetry points of Brillouin zone only for certain space groups. For these cases, the effect of strain is treated by symmetry considerations. The dependence of strain-induced potentials on the strain tensor is found. In all but two cases, the pseudomagnetic field potential is present. It can be used to control valley currents.
