摘要:

已知脏d波超导体的体微波电导率敏感地取决于无序势的范围:长程散射增强电导率,而短程散射没有影响。在这里,我们表明,正常金属d波超导体正常金属结的三端电导具有双重行为:短程散射抑制电导,而长程散射没有影响。

英文摘要:

The bulk microwave conductivity of a dirty d-wave superconductor is known to depend sensitively on the range of the disorder potential: long-range scattering enhances the conductivity, while short- range scattering has no effect. Here we show that the three-terminal electrical conductance of a normal-metal-d-wave superconductor-normal-metal junction has a dual behavior: short-range scattering suppresses the conductance, while long-range scattering has no effect.
