Multi-dimensional fs spectroscopy of an excitonic dimer, described by Redfield relaxation theory.

摘要

In non-linear spectroscopy, an optical signal is created by theinteraction of several short laser pulses with a medium. The main goal of suchexperiments is to relate the out-coming signal to the dynamical processes in thesystem under study. However, the relation between observables, like time- orfrequency spectra, and the underlying processes is often not straightforward. Inorder to understand and interpret the results, computer simulations are animportant tool.
