trailThe correlation spectrum measured at a BEC sonic horizon was thermal at the temperature predicted by Hawking's formula.
Spontaneous analogue Hawking radiation has been detected at sonic horizons in Bose-Einstein condensates.
The reported BEC analogue Hawking signal can be explained by amplified classical noise rather than quantum vacuum emission.
Planckian fit at the measured surface gravity· for
Steinhauer's Technion experiments observed correlated phonon pairs across a sonic horizon in a Bose-Einstein condensate.
A sonic horizon separating subsonic and supersonic flow can be created in a flowing Bose-Einstein condensate.
The cross-horizon density correlation signature was reproduced in successive Technion BEC experiments with improved statistics.
Simulations of BEC sonic horizons with thermal phonon populations reproduce the cross-horizon density correlation pattern.
The analogue Hawking radiation observed in the 2021 Technion experiment was stationary in time.

Theoretical models reproducing the 2019 BEC horizon correlation data predict significant departures from a thermal Hawking spectrum

Analogue gravity predicts that sonic horizons in flowing fluids emit thermal Hawking-like phonon radiation.
