Kwant code discussion
Dear author: I am a PHD student and my research is using pizeoelectric potential regulate spin and valley transport. I am quite intristed about Kwant and I have published an article on Nona Energy using Kwant I wonder could you please help me to solve the folowing two questions, the first one is how to calculate a one-dimensional quantum transport system, can you give a case? The second one is how to use Kwant to caculate heat transport system like electric current, heat current, temperature-dependent electrical conductance , the thermal conductivity, the Seebeck thermopower, and the thermoelectric efficiency. Could you give me an example? Thank you. Best wishes Ruhao Liu
Dear Ruhao,
Your first question is best addressed by following the tutorials. You
could find those in Kwant documentation
https://kwant-project.org/doc/1/tutorial/, however the recordings and
materials of this workshop may also be useful:
https://virtualscienceforum.org/quantum-transport-workshop/
There is no ready-made functionality in Kwant for computing the other
properties that you list. However combining the definition of these
properties with the scattering matrix, should allow you to implement
everything you need.
Best,
Anton

Dear Ruhao, Too complement Anton's reply, you can find some formulas for thermopower… directly implementable within Kwant in the attached article (see equation 9 and in the paragraph that follows). Best regards, Xavier
