Abstract
Dislocations and disclinations in a lattice of Josephson junctions will affect the dynamics of vortex excitations within the array. These defects effectively distort the space in which the excitations move and interact. We calculate the interaction energy between such defects and excitations, determine vortex trajectories in twisted lattices, and discuss the consequences for experiment.
