Yambo and charge density wave calcultaions

Post by sitangshu » Wed Feb 05, 2020 2:26 pm

Dear Yamboers,

Is it possible to calculate the charge density wave computations in yambo?

Regards,

Dear Sitangshu,
it is not totally clear what you mean here for "charge density wave computations", what exactly you need to compute?
In any case, please note that yambo read wave functions from the DFT ground state and these are not recomputed/updated with other approximations unless self-consistency is applied, but this feature at the moment has been not yet released.

Best,
Daniele
