Abstract
We report analytical and numerical results for delocking of flux-flow states in two magnetically coupled annular Josephson junctions (JJs). JJ stacks with different damping parameters are considered. An analyti cal model of the delocking is developed for dense fluxon chains. Analy tically predicted and numerically found delocking thresholds are in go od agreement.
