British scientists have created a novel experimental platform for the first time, namely “quantum tornado”.It can simulate the black holes in the super -flowing body, enabling researchers to observe the behavior similar to black holes and interact with the surrounding environment.Through the observation of superwave dynamics on the surface of the supercopy, researchers believe that these “quantum tornado” simulate the gravitational conditions near the rotating black hole.The study was published in the magazine of nature on the 20th.
In order to build a quantum simulator, researchers used ultra -flow bodies.The viscosity of ultra -flowing bodies is extremely low, only one fifth of the water.Because it has no friction during exercise, this form of 氦 shows an unusual quantum effect and is called a quantum fluid.Researchers put the pupa in a jar with a propeller.With the rotation of the propeller, the ultra -flow body forms a vortex similar to the wind.
The team builds a customized low-temperature system that can accommodate a few liters of overcurrent at a temperature below -271 ° C.At this temperature, the liquid 了 obtained unusual quantum properties.
Dr. Patrick Swancala, the main author of the thesis and the School of Mathematics of the University of Nottingham, said that the supercopic 氦 contains small objects called quantum vortex, and they often diffuse from each other.In the new device, tens of thousands of such quantums have been successfully limited in a compact object similar to small tornado, and the vortex of the intensity breaking records in the quantum fluid field is realized.
Researchers discovered the similarities of the influence of vortex and black holes on the surrounding space -time gravity.This result has opened up new ways to simulate limited temperature quantum field theory in the complex areas of curved space -time.
