Measurement of analogue Hawking radiation stimulated by a single photon
Hawking radiation is a fundamental spontaneous phenomenon in which the event horizon of a black hole transforms the vacuum state into a pair of correlated particles: the Hawking radiation and its partner. This emission can also be stimulated by a state other than the vacuum. A similar phenomenon, known as analogue Hawking radiation, has been observed across various physical systems, but experimental realizations have largely remained in the classical regime. This work present
Scientists have experimentally demonstrated a phenomenon analogous to Hawking radiation, but stimulated by a single photon rather than a black hole's event horizon. This breakthrough was achieved using heralded single photons to trigger the analogue Hawking effect within an optical fiber. The researchers then characterized the resulting Hawking signal by analyzing its spectral properties, intensity, and correlation patterns.
This experiment provides a new platform for investigating quantum correlations and entanglement in analogue gravity systems, opening avenues for research in nonlinear optics and quantum physics.
