Srovnání poruchových a neporuchových přístupů k teorii optické spektroskopie
Malý, Pavel ; Mančal, Tomáš (advisor) ; Pšenčík, Jakub (referee)
This thesis focuses on the comparison of perturbative and non-perturba-tive calculation of the third order polarization in two dimensional (2D) optical spec- troscopy. A two-level molecule and a coupled dimer are chosen as simple systems for which the 2D spectrum is calculated using explicit equations of motion for the reduced density matrix and integrating the response functions. The two approaches are compared qualitatively and quantitatively using obtained re- sults. The main difference found is the presence of higher order polarization contributions in non-perturbatively calculated spectrum. 1
