Kerr tutorial

[sitangshu]

Dear Yambo team,

In the old website, there was a tutorial on MOKE and Kerr effect. But I don't see it here. Can you please upload this again. I wish to learn it.

Regards,
Sitangshu

Dear Sitangshu,
Moke and kerr tutorials were quite old tutorials that need revision in order to be run with the new source. Actually we are restructuring the entire website and it should be ready in the next week. I hope that we could also upload a revised version of that tutorial.
Best,
Daniele

Thank you Danielle. In the new website, you may temporarily upload the old moke tutorial untill the the new one arrives.

Sitangshu

Dear Sitangshu,
we will try to upload it soon, the tutorials are now in the wiki part of the website, and probably it needs a format conversion, and it takes some time.
I will verify that, anyway I cannot tell you exactly when it will happen, hopefully soon.

Dear Danielle,

Thanks for your reply. Incidentally, I am trying to calculate the Kerr coefficients and AHC for an insulator (with a small GW gap ~0.5 eV) with no magnetization but a strong spin orbit coupling. Can I expect a large AHC in this case? I know that for magnetic metals, it can be large: PRB, 86, 125139 (2012).

Dear Sitangshu,
this forum is meant to support users when they have issues or they need help with the code.

The question you ask is, instead, whether a non magnetic system can have Kerr coefficients or an AHC different from zero.
This is a question of physics and I'm afraid we are not able to answer that.
As a first guess I'd say no, but again, one should study the physics of the problem to figure out.

Kind regards,
Davide
