New paper: electron transport in nodal line semimetals

October 11, 2017

Together with Sergey Syzranov, I studied the conductivity of nodal line semimetals. These turn out to be qualitatively different from other semimetals, like Weyl or Dirac semimetals, because of an unusual screening that changes the nature of the Coulomb potential from 1/r to 1/r^2.  Most dramatically, the nodal point is preserved against "spoiling" by charge disorder, and the mobility diverges at low energy.
