Abstract
The quantum transport of vortices in very long and narrow arrays of sm all Josephson junctions is studied experimentally. We investigate the forming of a Mott insulator in periodic arrays. When the vortex densit y is commensurate with the one-dimensional periodic potential, the vor tices localize due to the strong repulsive vortex-vortex interaction. We explore the influence of interaction strength, bandwidth, sample ge ometry, and temperature on the stability of the Mott states.
