Please note that you need a version of ATOM capable of generating vdw pseudopotentials.

In particular, the version of ATOM distributed with the 3.X series of SIESTA *cannot* generate vdw pseudopotentials. You need a more recent version. If you work in an academic setting, you can download ATOM from the main SIESTA webpage (www.icmab.es/siesta).

I do not see where is Atom program on the main Siesta webpage.

Can anyone share some vdw pseudopotentials for atoms such as H, C, Si,...? Thank you in advance.

Hi, this is an interesting question.
How will vdW affect the pseudopotentials ? Are there any literatures on this ?
Using the vdW pseudopotentials, how does it affect the calculation?

Can you help with this problem?
