论文摘要
通过在两波段超导体中为单个涡流状态的Bogoliubov-DE基因方程式求解，我们证明，即使在磁场和几乎超出了近距离的机构中，两种促成冷凝物的愈合长度之间的差异也受到带费速度的差异的强烈影响。更改带速度的比率改变了冷凝水长度的温度依赖性，并显着移动了``长度尺度锁定''''''''''''''''''''
By numerically solving the Bogoliubov-de Gennes equations for the single vortex state in a two-band superconductor, we demonstrate that the disparity between the healing lengths of two contributing condensates is strongly affected by the band Fermi velocities, even in the presence of the magnetic field and far beyond the regime of nearly zero Josephson-like coupling between bands. Changing the ratio of the band Fermi velocities alters the temperature dependence of the condensate lengths and significantly shifts parameters of the ``length-scales locking" regime at which the two characteristic lengths approach one another.
