Excitonic optical spectrum of semiconductors obtained by time-dependent density-functional theory with the exact-exchange kernel
Yong-Hoon Kim, Andreas Goerling
Applying the novel exact-exchange (EXX) Kohn-Sham method within time-dependent density-functional theory, we obtained the optical absorption spectrum of bulk silicon in good agreem…

Exact Kohn-Sham exchange kernel for insulators and its long-wavelength behavior
Yong-Hoon Kim, Andreas Goerling
We present an exact expression for the frequency-dependent Kohn-Sham exact-exchange (EXX) kernel for periodic insulators, which can be employed for the calculation of electronic re…

Optical excitations of Si by time-dependent density-functional theory based on the exact-exchange Kohn-Sham band structure
Yong-Hoon Kim, Martin Staedele, Andreas Goerling
We calculate the imaginary part of the frequency-dependent dielectric function of bulk silicon by applying time-dependent density-functional theory based on the exact-exchange (EXX…
