trailAmplification of thermal or classical fluctuations at a sonic horizon can produce cross-horizon correlations resembling spontaneous Hawking radiation.
The reported BEC analogue Hawking signal can be explained by amplified classical noise rather than quantum vacuum emission.
Linear mode-conversion mechanism· for
Mode conversion at an analogue horizon amplifies incident fluctuations regardless of their quantum or classical origin.
atomic
Simulations of BEC sonic horizons with thermal phonon populations reproduce the cross-horizon density correlation pattern.
atomic
Experimental demonstrations of stimulated Hawking emission· for
Stimulated Hawking emission has been measured at analogue horizons in water-wave experiments.
atomic
Stimulated analogue Hawking radiation has been observed in nonlinear optical systems.
