However, in most cases, these collective quantum states are fragile, with a short decoherence and dephasing time, limiting their existence to precision tailored structures under delicate conditions such as cryogenic temperatures and/or high magnetic fields. In this work, we discovered that the archetypal hybrid perovskite, MAPbI3 thin film, exhibits such a collective coherent quantum many-body phase, namely superfluorescence, at 78 K and above. Pulsed laser excitation first creates a population of high-energy electron–hole pairs, which quickly relax to lower energy domains and then develop a macroscopic quantum coherence through spontaneous synchronization. The excitation fluence dependence of the spectroscopic features and the population kinetics in such films unambiguously confirm all the well-known characteristics of superfluorescence. These results show that the creation and manipulation of collective coherent states in hybrid perovskites can be used as the basic building blocks for quantum applications4,5. A collective coherent quantum many-body phase, namely superfluorescence, is observed in CH3NH3PbI3 at 78 K. The excitation fluence dependence of the spectroscopic features and the population kinetics confirm all its well-known characteristics.}, number={9}, journal={Nature Photonics}, publisher={Springer Science and Business Media LLC}, author={Findik, Gamze and Biliroglu, Melike and Seyitliyev, Dovletgeldi and Mendes, Juliana and Barrette, Andrew and Ardekani, Hossein and Lei, Lei and Dong, Qi and So, Franky and Gundogdu, Kenan}, year={2021}, month={Jun}, pages={676–680} } @article{li_zeidell_findik_dunlap-shohl_euvrard_gundogdu_jurchescu_mitzi_2019, title={Phase-Pure Hybrid Layered Lead Iodide Perovskite Films Based on a Two-Step Melt-Processing Approach}, volume={31}, ISSN={["1520-5002"]}, DOI={10.1021/acs.chemmater.9b01265}, abstractNote={Layered lead halide perovskites have recently been heavily investigated due to their versatile structures, tunable electronic properties, and better stability compared with 3D perovskites and have ...}, number={11}, journal={CHEMISTRY OF MATERIALS}, author={Li, Tianyang and Zeidell, Andrew M. and Findik, Gamze and Dunlap-Shohl, Wiley A. and Euvrard, Julie and Gundogdu, Kenan and Jurchescu, Oana D. and Mitzi, David B.}, year={2019}, month={Jun}, pages={4267–4274} } @article{dunlap-shohl_barraza_barrette_dovletgeldi_findik_dirkes_liu_jana_blum_you_et al._2019, title={Tunable internal quantum well alignment in rationally designed oligomer-based perovskite films deposited by resonant infrared matrix-assisted pulsed laser evaporation}, volume={6}, ISSN={["2051-6355"]}, DOI={10.1039/c9mh00366e}, abstractNote={RIR-MAPLE enables thin-film deposition of organic–inorganic materials with tunable synergistic photophysics.}, number={8}, journal={MATERIALS HORIZONS}, author={Dunlap-Shohl, Wiley A. and Barraza, E.
