      abstract     = {We discuss the modelling of grain boundary dynamics within
                      an amplitude equations description, which is derived from
                      classical density functional theory or the phase field
                      crystal model. The relation between the conditions for
                      periodicity of the system and coincidence site lattices at
                      grain boundaries is investigated. Within the amplitude
                      equations framework, we recover predictions of the
                      geometrical model by Cahn and Taylor for coupled grain
                      boundary motion, and find both ⟨100⟩ and ⟨110⟩
                      coupling. No spontaneous transition between these modes
                      occurs due to restrictions related to the rotational
                      invariance of the amplitude equations. Grain rotation due to
                      coupled motion is also in agreement with theoretical
                      predictions. Whereas linear elasticity is correctly captured
                      by the amplitude equations model, open questions remain for
                      the case of nonlinear deformations.},
