Cascade of parametric resonances in coupled Josephson junctions

Cascade of parametric resonances in coupled Josephson junctions

We found that the coupled system of Josephson junctions under external electromagnetic radiation demonstrates a cascade of parametric instabilities. These instabilities appear along the IV characteristics within bias current intervals corresponding to Shapiro step subharmonics and lead to charging i...
