Bright-dark exciton splitting in lead halide perovskite crystals accessed via quantum beats in photon echoes
M. Alex Hollberg, Mikhail O. Nestoklon, Artur V. Trifonov +7
Understanding the fine structure of excitons is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization-sensit…

Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…

Spin-dependent exciton-exciton interactions in a mixed lead halide perovskite crystal
Stefan Grisard, Artur V. Trifonov, Thilo Hahn +6
We investigate the two-pulse photon echo response of excitons in the mixed lead halide perovskite crystal \sample in dependence on the excitation intensity and polarization of the…
