==Analog gravity models and surface gravity waves==

Surface gravity waves have been recognized as a powerful tool for studying analog gravity models, providing experimental platforms for phenomena typically found in black hole physics. In an experiment, surface gravity waves were utilized to simulate phase space horizons, akin to event horizons of black holes. This experiment observed logarithmic phase singularities, which are central to phenomena like Hawking radiation, and the emergence of Fermi-Dirac distributions, which parallel quantum mechanical systems.<ref>{{Cite journal |last1=Rozenman |first1=Georgi Gary |last2=Ullinger |first2=Freyja |last3=Zimmermann |first3=Matthias |last4=Efremov |first4=Maxim A. |last5=Shemer |first5=Lev |last6=Schleich |first6=Wolfgang P. |last7=Arie |first7=Ady |date=2024-07-16 |title=Observation of a phase space horizon with surface gravity water waves |journal=Communications Physics |volume=7 |issue=1 |pages=165 |doi=10.1038/s42005-024-01616-7 |issn=2399-3650 |doi-access=free }}</ref>

By propagating surface gravity water waves, researchers were able to recreate the energy wave functions of an inverted harmonic oscillator, a system that serves as an analog for black hole physics. The experiment demonstrated how the free evolution of these classical waves in a controlled laboratory environment can reveal the formation of horizons and singularities, shedding light on fundamental aspects of gravitational theories and quantum mechanics.
