Overview

• An international team observed soliton formations in hybrid perovskite materials that trigger superfluorescence at room temperature.
• They demonstrated that when excited polarons exceed a density threshold, they organize into ordered solitons that dampen thermal interference.
• Optical experiments directly tracked polaron populations transitioning from incoherent phases to coherent soliton states, confirming high-temperature macroscopic quantum coherence.
• Complementary simulations of lattice oscillations and recombination dynamics validated that solitons maintain coherence despite thermal noise.
• Published in Nature with U.S. Department of Energy support, the findings offer guidelines for engineering high-temperature quantum materials for communication, sensing and computing.
