Frequency-dependent Polarizability

Postby dscullion12 » Fri Dec 07, 2018 11:48 am

Dear VASP users,

It is possible to obtain the real and imaginary frequency-dependent dielectric function using the LOPTICS tag at DFT level and also by carrying out a GW calculation. I am wondering if it is also possible to output the frequency-dependent polarizability either at DFT or GW level. At GW the independent particle polarizability is used in the calculation of the screened Coulomb interaction. Is there a tag to output the data?

Thanks in advance for any help you can provide.

All the best,

Declan
