Simulating exciton migration and annihilation dynamics in higher order spectroscopies of a molecular trimer

Abstrakt

We present simulations of 3rd and 5th order multidimensional time-dependent signals of a molecular trimer. The developed model allows for the simulation of both signal types within one theoretical framework.

We therefore extended standard Redfield theory of exciton migration by a new term to include the process of exciton-exciton annihilation.
