Frenkel biexcitons in hybrid HJ photophysical aggregates
By using nonlinear coherent spectroscopy, we identify bound Frenkel biexcitons in a model polymeric semiconductor and find, unexpectedly, that excitons with interchain vibronic dispersion reveal intrachain biexciton correlations and vice […]
Stochastic scattering theory for excitation-induced dephasing: Comparison to the Anderson–Kubo lineshape
Quantum dephasing is a universal phenomenon in which the quantum system loses coherence over time due to interactions with the surrounding environment. In this article, we introduced a stochastic scattering […]
Enhanced screening and spectral diversity in many-body elastic scattering of excitons in two-dimensional hybrid metal-halide perovskites
We dive deeper into the rich many-body physics at the heart of excitons, primary photoexcitations, in two-dimensional lead-halide perovskites. Their polaronic nature, already a product of exciton-phonon interactions, is revealed […]
Phonon coherences reveal the polaronic character of excitons in two-dimensional lead halide perovskites
We believe these results to be the first direct evidence of the polaronic nature of excitons in 2D-HOIPs: each line of their excitonic fine structure corresponds to a distinct exciton-polaron. […]
