Exciton Dynamics, Relaxation, and Coherence

Model exciton transport using a drift-diffusion equation and relate mobility to momentum relaxation time.

Describe radiative and non-radiative recombination mechanisms (e.g., Auger processes) and their impact on exciton lifetime.

Analyze phonon-assisted relaxation processes between exciton states using Fermi's golden rule.

Calculate the temperature-dependent homogeneous line broadening of an excitonic transition due to exciton-phonon scattering.

Model time-resolved photoluminescence data using rate equations to extract population dynamics and relaxation rates.
