Researchers have, for the first time, identified the sufficient and necessary conditions that the low-energy limit of quantum gravity theories must satisfy to preserve the main features of the Unruh effect.
In a new study, led by researchers from SISSA (Scuola Internazionale Superiore di Studi Avanzati, the Complutense University of Madrid and the University of Waterloo, a solid theoretical framework is provided to discuss modifications to the Unruh effect caused by the microstructure of space-time.
The Unruh effect, named after the Canadian physicist who theorized it in 1976, is the prediction that someone who has propulsion and hence accelerates would observe photons and other particles in a seemingly empty space while another person who is inertial would see a vacuum in that same area.
