Query: Thermal conductivity and impurity scattering in the accreting neutron
  star crust   We calculate the thermal conductivity of electrons for the strongly
correlated multi-component ion plasma expected in the outer layers of neutron
star's crust employing a Path Integral Monte Carlo (PIMC) approach. This allows
us to isolate the low energy response of the ions and use it to calculate the
electron scattering rate and the electron thermal conductivity. We find that
the scattering rate is enhanced by a factor 2-4 compared to earlier
calculations based on the simpler electron-impurity scattering formalism. This
findings directly impacts the interpretation of thermal relaxation observed in
transiently accreting neutron stars and has implications for the composition
and nuclear reactions in the crust that occur during accretion.
