Excitonic effects in time-dependent density-functional theory: An analytically solvable model

R. Stubner, I. V. Tokatly, O. Pankratov

We investigate the description of excitonic effects within time-dependent density-functional theory (TDDFT). The exchange-correlation kernel f_xc introduced in TDDFT allows a clear…
