Geometrical Defects in Josephson Junction Arrays
arXiv:cond-mat/9903337 · doi:10.1103/PhysRevB.60.4334
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. The interaction energy between such defects and excitations are determined and vortex trajectories in twisted lattices are calculated. Finally, possible experiments observing these effects are presented.
