# The interplay between memory and potentials of mean force: A discussion on the structure of equations of motion for coarse-grained observables

@article{Glatzel2021TheIB, title={The interplay between memory and potentials of mean force: A discussion on the structure of equations of motion for coarse-grained observables}, author={Fabian Glatzel and Tanja Schilling}, journal={Europhysics Letters}, year={2021}, volume={136} }

The underdamped, non-linear, generalized Langevin equation is widely used to model coarse-grained dynamics of soft and biological materials. By means of a projection operator formalism, we show under which approximations this equation can be obtained from the dynamics of the underlying microscopic system and in which cases it makes sense to introduce a potential of mean force. We discuss shortcomings of previous derivations presented in the literature and demonstrate the implications of our…
