Breathers in solitonic room-temperature superlattice-induced superfluorescence in quasi-2D perovskites
A. A. Gladkij, N. N. Rosanov, B. D. Fainberg
Recently, a soliton mechanism for room-temperature superfluorescence in thin perovskite films has been proposed, with a fundamental soliton predicted to remain stable under LO phon…

Stability of the Quantum Coherent Superradiant States in Relation to Exciton-Phonon Interactions and the Fundamental Soliton in Hybrid Perovskites
A. A. Gladkij, N. A. Veretenov, N. N. Rosanov +3
The use of macroscopic coherent quantum states at room temperature is crucial in modern quantum technologies. In light of recent experiments demonstrating high-temperature superflu…

Exciton pairs coupled via the long-living phonons and their superfluorescent markers
Vladimir Al. Osipov, Boris Fainberg
A system of several Wannier-Mott excitons interacting with phonons in a bulk material is considered. We show that strong exciton-phonon coupling causes the formation of a coherent…
