Abstract
Identifying the relevant dynamics of solids that give rise to friction is an active field of study. It includes electronic and phononic degrees of freedom, but the latter seems to be of particular significance. For instance, drastic changes of friction on solids near phase transitions have been repeatedly measured. This phenomenon is attributed to sudden changes in the dynamics of phonons. The exact mechanism is, however, still poorly understood with many unanswered as well as yet-to-be-uttered questions. With this in mind, this thesis starts with asking; what are the roles of hidden phononic degrees of freedom when it comes to friction? We thus quantitatively study how friction arises from phonon dynamics of solids by means of both analytical and numerical methods.
