摘要:

本文在白噪声源作用下的sine-Gordon模型框架下研究了长重叠约瑟夫森结的瞬态动力学。对于过阻尼sine-Gordon方程,观察到了噪声延迟衰减效应。结果表明,这种噪声引起的效果,在小的噪声强度的范围内,消失的结长度大于几个约瑟夫森穿透长度。

英文摘要:

The transient dynamics of long overlap Josephson junctions in the frame of the sine-Gordon model with a white noise source is investigated. The effect of noise delayed decay is observed for the case of overdamped sine-Gordon equation. It is shown that this noise induced effect, in the range of small noise intensities, vanishes for junctions lengths greater than several Josephson penetration length.
