Query: The influence of defects on the thermal conductivity of compressed LiF   Defect formation in LiF, which is used as an observation window in ramp and
shock experi- ments, has significant effects on its transmission properties.
Given the extreme conditions of the experiments it is hard to measure the
change in transmission directly. Using molecular dynam- ics, we estimate the
change in conductivity as a function of the concentration of likely point and
extended defects using a Green-Kubo technique with careful treatment of
size-effects. With this data, we form a model of the mean behavior and its
estimated error; then, we use this model to predict the conductivity of a large
sample of defective LiF resulting from a direct simulation of ramp compression
as a demonstration of the accuracy of its predictions. Given estimates of
defect densities in a LiF window used in an experiment, the model can be used
to correct the observations of thermal energy through the window. In addition,
the methodology we develop is extensible to modelling, with quantified
uncertainty, the effects of a variety of defects on thermal conductivity of
solid materials.
