ABSTRACT
The most important effect in interactions between several Josephson junctions is doubtless their mutual phase locking (“synchronization”), i.e., the formation of their coherent state. This state of an array consisting of N junctions should be defined (see Reference 1) as one where not only the average Josephson oscillation frequencies ωJ (1.24) of the junctions, but also their slow frequencies ()https://www.w3.org/1998/Math/MathML">ωn ≡ Θ˙n = ϕ˙^n,n = 1, 2 … , N,https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315141572/0ba78ca1-05bc-4a29-bdf3-856e8fbc4b17/content/eq1385.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
