[QE-users] Possibility of jump in k-points in Bandstructure

[Vahid Askarpour]

Dear QE community,

I tried to reproduce the Si phonon dispersion along G-K-X-G-L in the following link (http://exciting-code.org/lithium-phonon-and-thermal-properties-si). The point K appears to be actually U. It seems that their code allows to jump from U to K (which are energetically equivalent but are distant from each other) without any gap along the k-path (x-axis). So they go from G to U, then jump from U to K and continue up to L.

Is it possible in QE to jump from one high symmetry point U to another point K and not have a k-distance gap along the x-axis when calculating band structure?

Thanks,

Vahid
