薄膜超导体中的运动珍珠涡旋

Moving Pearl vortices in thin-film superconductors

V. G. Kogan, N. Nakagawa

摘要:

利用含时的London方程研究了超导薄膜中运动珍珠涡旋在$(x,y)$平面内的磁场$h_z$。结果表明,对于沿$+x$方向运动的原点涡旋,$h_z(x,y)$在涡旋$x>0$的前方被抑制,在涡旋($x<0$)的后方被增强。分布的不对称性与正常准粒子的速度和电导率成正比。计算了涡的自能和两个运动涡的相互作用。

英文摘要:

The magnetic field $h_z$ of a moving Pearl vortex in a superconducting thin-film in $(x,y)$ plane is studied with the help of time-dependent London equation. It is found that for a vortex at the origin moving in $+x$ direction, $h_z(x,y)$ is suppressed in front of the vortex, $x>0$, and enhanced behind ($x<0$). The distribution asymmetry is proportional to the velocity and to the conductivity of normal quasiparticles. The vortex self-energy and the interaction of two moving vortices are evaluated.
