[QE-users] How and which vdWs functional to include for SOC calculation on a given 2D material

Hi everyone! I am trying to calculate SOC band-structure for a 2D material. I was able to do calculation without SOC using input_dft = "vdW-DF-obk8" However, by setting up SOC calculations using the following input tags I get the following error. Which type of vdW functional is compatible

[QE-users] Spontaneous polarization in monolayer

Hi , I reproduced your PRL paper on NbN monolayers https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.123.037601. I am following the steps as described by Quantum espresso example file on PbTiO3. But with this method, I am getting really weird numbers for polarization (really large
