Hello,

When I compare the electron density difference (excited state minus ground state) of a RT-TDDFT and a normal linear response TDDFT calculation they are quite different. For instance, given that the absorption spectra from both calculations are the same, if I do the RT-TDDFT calculation, shouldn't the electron density at the maximum of the dipole oscillation be the same as the static TDDFT calculation?

Thanks,
Stacey
