传统和非传统超导体间的Josephson隧道

Josephson Tunneling between Conventional and Unconventional Superconductors

运用准粒子自洽场方法计算了传统和非传统超导体间的Ｊｏｓｅｐｈｓｏｎ电流。计算表明临界电流极强地依赖于两个晶体和结的相对取向，并在某些特殊的相对取向变为零。同时证明，由于自旋轨道耦合。

The Josephson current among conventional and unconventional superconductors is calculated selfconsistently. The critical current depends strongly on the relative orientations among the two crystals and the junctions, vanishing in some special relative orientations. It is also show that, due to the spin orbit coupling, there is in general a finity Josephson current between a singlet and a triplet superconductor.
