What are the Kwantum Tornado? The movements of the electrons They can take very bizarre shapes. Even more in a quantum material. This was told by a team of physicists led by the University of Würzburg, Germany, which for the first time has been experimentally demonstrated how electrons can actually form Kwantum Tornado. Theirs discoveryPublished in the magazine Physical assessment XOne day a revolution could bring about in the world of electronics, open the way to “orbitony“, A new field that would be based on the power of running electrons, instead of their electrical charge, to transport information in electronic circuits or in quantum computersReducing energy losses.
Location and moment space
Science already knows that electrons can form swirls in special materials. However, the novelty of this study is the discovery, now experimental that these small particles create structures that are comparable to Tornado in moment. We remember briefly that the moment for physicists is a concept that the movement of the electrons In terms of energy and direction, instead of their exact physical position. In other words, that is why the moment of moment describes their movement through their energy and direction. The locationOn the other hand, it is Kingdom in which more well -known phenomena occur, such as water vertebrates or hurricanes. So far, however, me Kwantum Tornado They were only observed in the location room.
The experiment
Because, at least theoretical, physicists knew that quantum tornadoes could also form in space, and so far nobody knew How to measureThe researchers of the new study investigated one semimetallic crystalcalled Arseniuro di Tantalio, whose special quantum properties make the choice, in fact, in fact, to find quantum tornadoes. To do this, they perfected a technique called photo mission spectroscopy in the corner (Arpes). “Arpes is a fundamental tool in the experimental physics of the fixed state. It consists of illuminating a sample of material, extracting electrons and measuring its energy and the exit corner “, The co-author Maximilian Ünzelmann explained. “This offers us a direct look at the electronic structure From a material in the space of the moment. By adjusting this method intelligent, we were able to measure the orbital corner moment “. Their experiments in fact revealed that the Kwantum Vortex was made from the angular orbital moment, or the circular movement of electrons Around the atomic cores.
Kwantum Tornadoes
However, each observation was only a kind of two dimensional momentane of the electrons in the material and to confirm the existence of quantum tornadoes, the team had to be in a measurement in one 3D -Model. “We have analyzed the low sample per layer, in a similar way to the medical“Ünzelmann explained. “By combining the individual images together, we were able to reconstruct the three -dimensional structure of the orbital corner moment and confirm that electrons vertebra in the space of the moment“. From here, the team hopes that further studies can not only lead to more efficient electronics, but also to A completely new class devices called Orbitronic.
