Abstract:
We report on a nontrivial type of slow-fast dynamics in a Josephson junction model externally shunted by a resistor and an inductor. For large values of the shunt inductance the slow manifold is highly folded, and different types of dynamical behavior in the fast variable are possible in dependence on the other parameters of the junction. We discuss how particular features of the dynamics are manifested in the current-voltage characteristics of the shunted junction.Received: 10 March 2003, Published online: 11 August 2003PACS: 05.45.-a Nonlinear dynamics and nonlinear dynamical systems - 85.25.Cp Josephson devices - 74.81.-g Inhomogeneous superconductors and superconducting systems
