Query: Conductivity in nodal line semimetals with short-ranged impurity
  potentials   We study the transport properties in nodal line semimetals with short-ranged
impurity potentials at zero temperature. By computing the Drude conductivity
and the corrections from the interference of particle and hole trajectories, we
find that the electrons are localized in directions both parallel and
perpendicular to the plane of nodal ring. We further calculate the conductivity
in a weak magnetic field, and find that the perpendicular magnetic field
totally destroys the weak localization gives a positive quantum interference
correction, which is similar to the result in Weyl semimetals. But for a
parallel magnetic field, because of the $\pi$ Berry phase of the electron orbit
around the nodal line, the magnetoconductivity is negatively proportional to
$B$. The difference between the perpendicular and the parallel magnetic field
may be verified by experiments. Nodal line semimetals which break inversion and
time-reversal symmetry and have spin-orbit coupling are also considered and
produce qualitatively the same results.
