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.

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
