Story summary

At Rice University, researchers achieved room-temperature ultrastrong coupling between two phonon modes in lead halide perovskites and terahertz light.
The coupling ratio reached 30%, a major advance over prior cryogenic-only methods.
Nanoscale slots in gold films confine waves, enabling precise tuning of light-phonon interactions.
Nature Communications published work may boost solar cells and LEDs and open quantum-technology avenues.
