On the material frame indifference controversy: Some results from group theory and computer simulation.

Abstract

Group theory and computer simulation are used to show that molecular and atomic scale time cross correlation functions have different symmetry properties in different frames of reference. Constitutive equations, written in any frame of reference, are approximations to classical molecular dynamics, and must therefore reproduce the results from group theory applied to ensemble averages such as time correlation functions, and corroborated by computer simulation. This may help to resolve some of the contemporary literature claims regarding material frame indifference and the implementation of “co- rotating” frames.
