Ultrafast nonequilibrium evolution of excitonic modes in semiconductors
Physical Review B, 2020.
We study the time evolution of excitonic states after photo-excitation in the one-dimensional spinless extended Falikov-Kimball model. Several numerical methods are employed and benchmarked against each other: time-dependent mean-field simulations, the second-Born approximation (2BA) within the Kadanoff-Baym formalism, the generalized K...More
