Cavity Quantum Electrodynamics with Single Perovskite Quantum Dots: Assessing Rabi Coupling Strength, Pure Dephasing, and Spectral Diffusion
Zakaria Said, Marina Cagnon Trouche, Antoine Borel, Mohamed-Raouf Amara, Jakob Reichel, Christophe Voisin, Carole Diederichs and Yannick Chassagneux
Deterministic coupling of individual perovskite quantum dots to a tunable microcavity, with enhanced emission and a spectroscopic analysis of coupling, pure dephasing and spectral diffusion.

Spectral Fingerprint of Quantum Confinement in Single CsPbBr₃ Nanocrystals
Mohamed-Raouf Amara, Zakaria Said, Caixia Huo, Aurélie Pierret, Christophe Voisin, Weibo Gao, Qihua Xiong and Carole Diederichs
Cryogenic spectroscopy of individual CsPbBr₃ nanocrystals reveals how quantum confinement shapes exciton fine structure, trion and biexciton binding energies, and phonon replicas. The spectra and polarisation properties are interpreted through an exchange model and the orientation of the emitting dipoles.
