论文摘要
由于约瑟夫森系统与轴的耦合，我们讨论了约瑟夫森交界处的共振激活现象。我们展示了如何利用这种效果进行轴突检测。从超导到电阻状态与轴突能和约瑟夫森等离子能的比率的平均切换时间最小的非单调行为。我们证明了切换时间的变化如何使检测轴心场的存在成为可能。提出了一种通过与约瑟夫森系统耦合观察轴的实验协议。
We discuss the resonant activation phenomenon on a Josephson junction due to the coupling of the Josephson system with axions. We show how such an effect can be exploited for axion detection. A nonmonotonic behavior, with a minimum, of the mean switching time from the superconducting to the resistive state versus the ratio of the axion energy and the Josephson plasma energy is found. We demonstrate how variations in switching times make it possible to detect the presence of the axion field. An experimental protocol for observing axions through their coupling with a Josephson system is proposed.
