Topological semimetal with wanniertoos and Quantum Espresso

[Mostafa Ragragui]

Hello everyone and all.
I would first like to thank you for creating this website to share information about the wanniertools package and science in general. I am average working with wanniertools but I have not seen good surface states yet, I do not know why?
May be because i work with Quantum Espresso which is different from VASP?
The example I’m currently dealing with: is a topological semimetal (LaBi) and that’s what I found at (001) surface , it’s totally different from literature?
please help me find a solution, I make the maximum effort, I need to resolve this results?

suraface states of topological semimetal LaBi

best regards

1. Did you check with the topological number? If the topological number is not trivial, then the surface states must be nontrivial.
2. If the topological number is non-trivial, then please increase NP from 1 to 6 until the surface states spectrum don’t change any more.
