Re: [QE-users] NEB images with different cell parameters possible?

2019-09-06 Thread A. Jain
Sorry for not being clearer, the 'excited' state in our case is actually a metastable state, i.e. a stable state on its own that has undergone photoisomerisation via broadband light. I figured there wasn't variable cell neb. I thought to simply average the cell parameters and use them to condu

Some time ago there was a project of variable-cell NEB, but it went nowhere. Anyway: here the problem is not variable-cell NEB but a NEB between an initial configuration in the ground state and a final one in the excited state, if I understand correctly. This is just plain impossible. Paolo On F

Dear Apoorv Jain AFAIK, variable cell NEB is not implemented in QE (yet). HTH Giuseppe "A. Jain" ha scritto: Hi All, I would like to conduct an neb study on my system (ruthenium based crystals) where photoisomerisation takes place. We would like to investigate the mechanism of photoiso

Hi All, I would like to conduct an neb study on my system (ruthenium based crystals) where photoisomerisation takes place. We would like to investigate the mechanism of photoisomerisation. However the ground state and irradiated states (geometries obtained via accurate xrd experiments) have v
