Scientists finally created mysterious particles known as Shankar Sigmite. It has been more than 40 years since it was first proposed by the theory. Moreover, scientists may also have simulated a rare 'spherical lightning' phenomenon in this process. On the quantum scale, the researchers said that this discovery will not only help explain the mysterious natural phenomenon of spherical currents in the storm, but also may pave the way for more stable plasma in nuclear fusion reactors.
The new study was conducted by scientists from Amherst College and the Aalto University in Finland. The research team synthesized a three-dimensional sigmoid in a cryogenic quantum-state gas. This three-dimensional particle was created by Bose-Einstein. The kinks formed by the spin fields of agglomerates (a gaseous, superfluid matter state that boson atoms exhibit when cooled to near absolute zero) consist of kinks.
Researchers claim that this peculiar topology may have some features in common with ball lightning. 'In essence, it is incredible to create a synthetic electromagnetic kink, ie quantum ball lightning, using only two reverse-cycle currents. The head of research, Mikko Mttnen of Aalto University, said, 'Therefore, natural spherical lightning may form in ordinary lightning.'
In order to generate sigma, the researchers polarize the spin of each atom and deflect it upward along a natural magnetic field. Then, the magnetic field suddenly changes, causing the magnetic field in the middle of condensation to 'disappear', and then the spin of the atom begins. Rotate in a new direction. However, as you approach absolute zero and the magnetic field points in all directions, the atom's spin can create a kink structure that points in a fixed direction.
The researchers said that although the kink structure can relax or move, it cannot be opened. 'The quantum gas is cooled to an extremely low temperature, forming a Bose-Einstein condensate, that is, all atoms in the gas eventually reach the minimum energy. State,' David Hall of Amherst College said, 'The gas in this state no longer behaves like a normal gas, but more like a huge atom.'
'This is a sigma and not a quantum kink, not only because of the torsion of the spin, but also the re-entanglement of the condensed quantum states,' added Hall. The researchers also stated that the kink structure created by the spin of atoms creates A kinked artificial magnetic field emerged, which is consistent with the characteristics of the spherical lightning. 'We need more research to determine if we can use this method to create a spherical lightning bolt,' said Möttnen, 'future Research may find ways to keep the plasma together effectively and make stable nuclear fusion reactors possible.
What is a ball lightning?
For centuries, there have been records of spherical lightning in thunderstorms, some of which are only the size of a golf ball and some have a diameter of several meters. The duration of a spherical lightning varies from 1 second to several tens of seconds. Many reports said that This kind of lightning can harm or even cause death, or cause a building fire.
In a letter received by the British "Daily Mail" in 1936, a reader described him as seeing a 'great, red fireball in the sky'. 'It hit our house, cut it off. The telephone line, which had burned the window case, then fell into a large bucket of water underneath it,' writes Zengzhong. The researcher at Zhejiang University proposed that the bright flash of the ball lightning is due to the microwave being confined to the plasma vacuole. of.
'At the end of lightning strikes the ground, it generates relativistic electron beams that ignite strong microwave radiation,' the researchers wrote in a paper published in the journal Scientific Report, 'The latter will cause local air ionization. , and the radiation pressure evacuates the generated plasma to form a spherical plasma bubble that stably captures radiation.
The microwave trapped inside the cavitation continues to generate plasma for a period of time and maintains a bright flash of light during the ball lightning. As the radiation in the bubble begins to dissipate, the fireball gradually disappears when the microwave leaks. , Ball lightning may explode violently.
