Purcell-enhanced single-photon generation from CsPbBr quantum dots in in-situ selected Laguerre-Gaussian modes
Virginia Oddi, Darius Urbonas, Etsuki Kobiyama +9
Single photons in Laguerre-Gaussian (LG) beams, which carry orbital angular momentum (OAM), could enable more robust and efficient photonic quantum communication and information pr…

Radiation-Triggered Superfluorescent Scintillation in Quantum-Ordered Perovskite Nanocrystal Superlattices
Matteo L. Zaffalon, Andrea Fratelli, Taras Sekh +8
Superfluorescence, a cooperative emission phenomenon arising from the coherent coupling of excited dipoles, has historically been observed under optical excitation in carefully eng…

Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
