Optical response of small closed-shell sodium clusters
George Pal, Georgios Lefkidis, Hans Christian Schneider +1
Absorption spectra of closed-shell Na_2, Na_3+, Na_4, Na_5+, Na_6, Na_7+, and Na_8 clusters are calculated using a recently implemented conserving linear response method. In the fr…

Optical absorption spectra of finite systems from a conserving Bethe-Salpeter equation approach
George Pal, Yaroslav Pavlyukh, Wolfgang Hübner +1
We present a method for computing optical absorption spectra by means of a Bethe-Salpeter equation approach, which is based on a conserving linear response calculation for electron…
