Starting a YAMBO calculation from VASP DFT calculation

Hi,

I have been using VASP for a long time, and I want to do my DFT calculations with VASP first, then proceed with GW and other methods for exciton studies. I am just a beginner in YAMBO, what are the possibilities for this?

I recently heard that there is an option in p2y to convert a VASP WAVECAR file to a YAMBO-readable format. I am just confused about how to do this, as nothing was mentioned in the tutorials either.

Can anyone help me with the initial steps on this part?


Thanking you,
Snehith.

Dear Snehith,

Yambo it is not interfaced with VASP. The p2y utility is an interface for Quantum Espresso. So, for calculations with Yambo you can use QE for the ground state or alternatively Abinit and use a2y.

Note that GW method is also implemented in VASP.

Best,

Daniele
