Abstract
We generate and observe discrete rotobreathers in Josephson junction ladder s with open boundaries. Rotobreathers are localized excitations that persis t under the action of a spatially uniform force. We find a rich variety of stable dynamic states including pure symmetric, pure asymmetric, and mixed states. The parameter range where the discrete breathers are observed,in ou r experiment is limited by retrapping due to dissipation.
