Slow-fast dynamics in Josephson junctions
نویسندگان
چکیده
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.

Josephson Current For a Graphene Nanoribbon Using a Lattice Model
A tight binding approach based on the Bogoliubov-de Gennes approach has been used to calculate the DC Josephson current for a lattice model for S-GNR-S junctions , for short junctions with respect to superconducting coherence length. We calculate the phase, length, width and chemical potential dependence at the Josephson junction and discuss the similarities and differences with regard to the t...
متن کاملOn kink-dynamics of Stacked-Josephson Junctions
Dynamics of a fluxon in a stack of coupled long Josephson junctions is studied numerically. Based on the numerical simulations, we show that the dependence of the propagation velocity c on the external bias current γ is determined by the ratio of the critical currents of the two junctions J .
متن کاملJosephson junctions in charge and phase picture Theory and applications
Properties of weak links between two superconductors, or Josephson junctions, make them interesting for fundamental physics research. Since their discovery over four decades ago, they have provided a unique way to study the behavior of the superconducting quantum phase. More recently, ultra small, or mesoscopic, Josephson junctions with substantial single Cooper pair charging energy have gained...
متن کاملInfluence of Length on the Noise Delayed Switching of Long Josephson Junctions
Josephson junctions are physical systems with nonlinear dynamics, which are interesting to investigate both from experimental and theoretical points of view. This is also in view of numerous applications of superconductive devices based on Josephson junctions, such as RSFQ devices, qubits, SQUIDs, etc.. [Barone & Paternò, 1982; Likharev, 1986]. There are, in fact, a lot of open problems in Jose...
متن کاملNonadiabatic Josephson dynamics in junctions with in-gap quasiparticles
Conventional models of Josephson junction dynamics rely on the absence of low-energy quasiparticle states due to a large superconducting gap. With this assumption the quasiparticle degrees of freedom become «frozen out» and the phase difference becomes the only free variable, acting as a fictitious particle in a local in time Josephson potential related to the adiabatic and nondissipative super...
