Description
I will discuss the scattering from one-dimensional defects in
intrinsic graphene. It turns out that the Coulomb repulsion
between electrons can induce singularities of such scattering
at zero temperature like in one-dimensional conductors. In
striking contrast to electrons in one space dimension,
however, repulsive interactions here can enhance transport. I
will present explicit calculations for the scattering from vector
potentials that appear when strips of the material are under
strain. There the predicted effects are exponentially large for
strong scatterers.
