"Acoustic black holes: Horizons, ergospheres and Hawking radiation". Quantum, spontaneous Hawking radiation was observed later. In 2014, stimulated Hawking radiation was reported in an analogue black-hole laser by the same researchers. However, the scientists who created it predicted that the experiment was suitable for detection and suggested a method by which it might be done by lasing the phonons. The surface gravity and temperature of the sonic black hole were measured, but no attempt was made to detect Hawking radiation. This technique creates a flow by repelling the condensate with a potential minimum. It was created in a rubidium Bose–Einstein condensate using a technique called density inversion. However, the first black hole analogue was not created in a laboratory until 2009. Īcoustic black holes were first theorized to be useful by William Unruh in 1981. The fact that so many systems mimic gravity is sometimes used as evidence for the theory of emergent gravity, which could help reconcile relativity, and quantum mechanics. Gravity analogues other than phonons in a fluid, such as slow light and a system of ions, have also been proposed for studying black hole analogues. Many nearly perfect fluids have been suggested for use in creating sonic black holes, such as superfluid helium, one–dimensional degenerate Fermi gases, and Bose–Einstein condensate. The complexity of such a system would make it very difficult to gain any knowledge about such features even if they could be detected. Nearly any fluid can be used to create an acoustic event horizon, but the viscosity of most fluids creates random motion that makes features like Hawking radiation nearly impossible to detect. For this reason, a system in which a sonic black hole can be created is called a gravity analogue. Sonic black holes are possible because phonons in perfect fluids exhibit the same properties of motion as fields, such as gravity, in space and time. The boundary of a sonic black hole, at which the flow speed changes from being greater than the speed of sound to less than the speed of sound, is called the event horizon.Ī rotating sonic black hole was used in 2010 to give the first laboratory testing of superradiance, a process whereby energy is extracted from a black hole. On the other hand, the Hawking radiation can be stimulated in a classical process. This Hawking radiation can be spontaneously created by quantum vacuum fluctuations, in close analogy with Hawking radiation from a real black hole. Physicists are interested in them because they have many properties similar to astrophysical black holes and, in particular, emit a phononic version of Hawking radiation. They are called sonic, or acoustic, black holes because these trapped phonons are analogous to light in astrophysical (gravitational) black holes. Acoustic analogue of a black hole in which sound plays the role of lightĪ sonic black hole, sometimes called a dumb hole or acoustic black hole, is a phenomenon in which phonons (sound perturbations) are unable to escape from a region of a fluid that is flowing more quickly than the local speed of sound.
