Abstract

The present work is a theoretical study aiming at understanding the role of the electronic temperature on the optical response of simple metal clusters. The electronic temperature dependence of the optical response of simple metal clusters is investigated by many different quantum mechanical theories. The bulk dielectric functions are the most important quantities of a quantum many-electron system. Here we use of bulk dielectric function theory for calculating of longitudinal and transverse dielectric functions in the quantum many-electron system..

Keywords
