Diversity of discrete breathers observed in a Josephson ladder
arXiv:cond-mat/0004212 · doi:10.1103/PhysRevE.62.2858
Abstract
We generate and observe discrete rotobreathers in Josephson junction ladders with open boundaries. Rotobreathers are localized excitations that persist 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 our experiment is limited by retrapping due to dissipation.
