Hi Sayan,

Those links are for an old version of Kwant. In the current version you can compute spin transport by specifying conservation laws in the leads, similar to what the tutorial does with the superconductors: https://kwant-project.org/doc/1/tutorial/superconductors .

Best,

Anton

Dear developer,
I am looking for the calculation of spin Hall conductance in a four-terminal device. I am searching the mailing archives for a few days, but couldn't get anything useful. But, I found a thread where Mr Joseph Weston (https://mail.python.org/archives/list/kwant-discuss@python.org/message/MHYO2I2FTPTS4YF5VZLX3GDWVMO6NDCF/) had given some links for this calculation and unfortunately those links are not working. It would be very useful if you provide one example of calculating spin Hall conductance of a four-terminal device.

I shall look forward to your kind reply.

Thanking you.

Sincerely yours,
