[Kwant] Kwant-based tutorial: try it directly in your web browser
Dear users of Kwant, At this year’s APS March meeting the core Kwant team held an “Introduction to Computational Quantum Nanoelectronics” tutorial [1]. The bulk of the course consisted of hand-on work with Kwant-powered Jupyter notebooks that contain explanations, examples and exercises. The tutorial was attended by over 70 people and we received highly positive feedback for it. The complete set of the tutorial notebooks is now available online [2]. There is also a link that allows to execute the notebooks directly in a web browser without installing Kwant locally. Please feel free to check it out and do not hesitate to spread the word to anyone who might be interested, especially to people who are not using Kwant yet. Regards, Christoph on behalf of the whole tutorial team [1] http://www.aps.org/meetings/march/events/tutorials.cfm#t10 [2] http://kwant-project.org/mm16 smime.p7s Description: S/MIME cryptographic signature
[Kwant] Spin polarized transport calculation
Dear Kwant users and developers I have two questions related to the spin calculation using kwant. 1. I'm wondering if we can do spin-polarized transport in kwant? For example, can we can get the separate Conductance Vs Energy diagram for spin up and spin down terms. I'm thinking one way of doing this is to set up the Rashba Hamiltonian as a whole. And then manually extract the spin up and spin down hamiltonian and do the transport calculation separately. But this will eliminate some extra terms that I don't know whether this is correct anymore. Any suggestions? 2. How can we set up the spin polarization for a particular site? For example, in some of the topological insulator, can we set up spin polarization on the edge as up and the other side of the edge as down, and then do the transport? Or this question is completely wrong? Thanks for advance. Sincerely, Liming
