Summary

Story summary

Stockholm University and the Indian Institute of Science Education and Research Mohali (IISER Mohali) developed a method to detect the Unruh effect.
They use high-quality mirrors to amplify tiny quantum signals from atoms.
This enables atoms to emit light in a synchronized burst.
The burst occurs earlier when the atoms experience the slight warming associated with acceleration.
The research was published in Physical Review Letters on October 27, 2025.
