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
