Abstract: In the framework of time-dependent density functional theory (TDDFT), the exact exchangecorrelation (xc) kernel fxc(n, q, ω) determines the ground-state energy, excited-state energies, lifetimes, and the time-dependent linear density response of any many-electron system. The… read more here.
