Calculation of Electronic Excitation and Ionization Process in High-Tc Superconductors
In order to calculate the optical conductivity of HTSC, we first consider the optical response of related small clusters. In this way, the photoabsorption cross section of a CuO2 molecule is calculated in the TDLDA via one-centre expansion around the Cu site. The resulting absorption shows strong oscillations due to molecular structure.
