Generalized stability law for Josephson series arrays
نویسندگان
چکیده
By deriving an N-dimensional Poincare map, we explore the enhanced stability of Josephson series arrays using capacitive junctions. The analytic expression for the critical Floquet multiplier has a direct physical interpretation, affording new insight into the conditions that affect inphase stability. In particular, we generalize the well-known stability principle previously established for arrays of zero capacitance junctions. Optimally capacitive junction arrays offer a much improved candidate for experimental realization of the Kuramoto model. 2002 Elsevier Science B.V. All rights reserved.

Synchronization law for a van der Pol array.
We explore the transition to in-phase synchronization in globally coupled oscillator arrays, and compare results for van der Pol arrays with Josephson junction arrays. Our approach yields in each case an analytically tractable iterative map; the resulting stability formulas are simple because the expansion procedure identifies natural parameter groups. A third example, an array of Duffing-van d...

In the following work we present a proof for the strong law of large numbers for pairwise negatively dependent random variables which relaxes the usual assumption of pairwise independence. Let be a double sequence of pairwise negatively dependent random variables. If for all non-negative real numbers t and , for 1 < p < 2, then we prove that (1). In addition, it also converges to 0 in ....
متن کاملDevelopment of Josephson junction series arrays for synthesis of AC voltages and arbitrary waveforms
Josephson junctions operated by short pulses make the synthesis of AC and arbitrary waveforms possible. Series arrays of intrinsically shunted SINIS and SNS Josephson junctions were developed and characterized for applications in this Josephson arbitrary waveform synthesizer (S: Superconductor, I: Insulator, N: Normal conductor). First measurements under pulse irradiation are presented.
متن کاملStability of periodic solutions in series arrays of Josephson junctions with internal capacitance
A mystery surrounds the stability properties of the splay-phase periodic solutions to a series array of N Josephson junction oscillators. Contrary to what one would expect from dynamical systems theory, the splay state appears to be neutrally stable for a wide range of system parameters. It has been explained why the splay state must be neutrally stable when the Stewart-McCumber parameter β (a ...
متن کاملDevelopment of Josephson Voltage Standards
Exciting applications of superconductivity are based on the macroscopic quantum state which exists in a superconductor. In this chapter we investigate the behaviour of junctions consisting of two weakly coupled superconductors. These junctions are nowadays called Josephson junctions1 (Josephson, 1962). The macroscopic quantum state results in an exceptional behaviour of these Josephson junction...
