Chaos synchronization between the Josephson junctions governed by the central junction under the effect of parameter mismatches and noise
Abstract
Chaos synchronization between Josephson junctions driven by a central junction is studied under the parameter mismatches and noise. It is demonstrated that chaos synchronization quality is robust to 10-15 % parameter mismatches. It is also elucidated that for the intermediary noise intensity correlation between the synchronized junctions can be even enhanced; however for larger intensities of noise synchronization quality deteriorates. It is also established that synchronization quality between some junctions remains unchanged, despite the fact that all the driven junctions and the driver junction were subject to the same amount of noise. These results are of certain importance for obtaining the high power system of Josephson junctions in real-life situations and are promising for practical applications in the Terahertz region.
