Shape of a moving fluxon in stacked Josephson junctions
Shape of a moving fluxon in stacked Josephson junctions
We study numerically and analytically the shape of a single fluxon moving in a double stacked Josephson junctions (SJJ's) for various junction parameters. We show that the fluxon in a double SJJ's consists of two components, which are characterized by different Swihart velocities and Josephson penetration depths. The weight coefficients …
