Analog models of gravity are attempts to model various phenomena of general relativity (e.g., black holes or cosmological geometries) using other physical systems such as waves in a moving fluid and electromagnetic waves in a dielectric medium.
[2] It has been shown that Bose-Einstein condensates (BEC) are a good platform to study analog gravity.
[3] Rotating blackholes described by Kerr metric have been implemented in a BEC of exciton-polaritons (a quantum fluid of light).
Recent experiments have demonstrated that these waves can effectively simulate phase space horizons, drawing parallels to black hole physics.
Specifically, the use of surface gravity water waves has enabled the observation of logarithmic phase singularities and the onset of Fermi–Dirac statistics, phenomena typically associated with quantum systems and gravitational theories.
