参数失配和噪声影响下中心结控制的约瑟夫森结间的混沌同步
Chaos synchronization between the Josephson junctions governed by the central junction under the effect of parameter mismatches and noise
摘要：
研究了在参数失配和噪声作用下，中心结驱动的约瑟夫森结之间的混沌同步。实验结果表明，混沌同步质量对10- 15%的参数失配具有鲁棒性.它还阐明，对于中间的噪声强度之间的相关性同步的路口，甚至可以增强，然而，对于更大的噪声强度同步质量恶化。它还建立了一些结之间的同步质量保持不变，尽管事实上，所有的驱动结和驱动器结受到相同量的噪声。这些结果对于在实际应用中获得高功率的约瑟夫森结系统具有一定的意义，并有望在太赫兹波段得到实际应用。
英文摘要：
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.
