Frequency-dependent Polarizability
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
