摘要
讨论了约瑟夫逊结中噪声驱动下电流的线性响应 .理论结果表明 :随着噪声自关联时间τ的增大 ,平均归一化电压减小 ;热涨落参量越大 ,平均归一化电压减小越缓慢 .就驱动电流的线性响应而言 。
The linear responses of driving current in Josephson junction are studied.The theoretical results show that the mean normalization v oltage is decreased with autocorrelatoin time of noise increasing,and the mean normalization voltage decreases slowly with the thermal fluctuations parameter increasing.The effects of the white noise are opposite to the O-U noise in the linear responses of driving current.
