Macroscopic laser–plasma interaction under strong non-local transport conditions for coupled matter and radiation Open
Reliable simulations of laser–target interaction on the macroscopic scale are burdened by the fact that the energy transport is very often non-local. This means that the mean-free-path of the transported species is larger than the local gr…
