Nonlocal Electron Heat Transport by Not Quite Maxwell-Boltzmann Distributions

We have made numerical calculations with a new nonlocal fluid treatment of Coulomb collisional electron transport which self-consistently accounts for the nonthermal high-energy electrons arising from the spatial transport of thermal electrons whose range is not short compared with the temperature scale length. Heat fluxes associated with steep gradients are reduced from classical, while ahead of a temperature front there is preheating which exceeds classical.
