In recent years several efforts towards the detection of analogue Hawking radiation have been carried out
with different physical systems. Here we report a brief list of the ongoing efforts. There is already
definite evidence for mode conversion and negative-norm modes (group velocity opposite to
phase velocity) [532], and more recently for stimulated Hawking emission [682
]. There are very
recent claims of photon detection from a phase velocity horizon in an optical fibre [66
], and for
white-hole–like behaviour in hydraulic jumps [334
]. It seems that reliable and reproducible
experimental probes of spontaneous quantum Hawking radiation might be just a few years in the
future.
