At the smallest scales, particles follow the rules of quantum physics. Large groups of particles usually lose these quantum features, unless they are cooled to very low temperatures, as in superconductors.

What they work on
- Discover hybrid metal halide perovskite materials that show room-temperature superfluorescence, a collective burst of coordinated light emission, with colors tunable across the visible spectrum.
- Calculate electron–electron and electron–lattice interactions with first-principles theory and computer simulations, to explain how material structure controls superfluorescence.
- Link superfluorescence features such as critical temperature, threshold excitation density and coherence to material properties, and deposit the resulting data in the open HybriD3 database.
More about the research
Superfluorescence is a related collective quantum effect. Many light emitters lock together and release a single intense, coordinated burst of light. Surprisingly, it has been seen at room temperature in hybrid materials made of lead halide perovskites, a family of light-emitting crystals, combined with organic molecules. This project seeks to find which hybrid materials can show room-temperature superfluorescence, with colors tunable across the visible spectrum.
Why it matters
Room-temperature superfluorescence could make quantum optical effects practical without costly cooling. That could help build sources of entangled photons and tunable, intense light for photonic devices. Open data in the HybriD3 database could help other materials researchers design hybrid quantum emitters.
Known grants
