The British journal Nature published a major breakthrough in the field of topological state research online on the 19th, the Chinese Academy of Sciences Institute of Physics research team found triple simple and Fermizi, this is the first discovery to break the conventional classification of the new Fermi, for solid materials in the electronic topological state research opened up a new direction.
particles that make up the universe can be divided into bosons and fermis.
ferns are the raw materials that make up matter, and the bosons transmit forces.
existing theory that there may be three types of Fermizis in the universe: Dirac Fermizi, Erfemizi, and Mayorana Fermizi.
scientists have been trying to find new Fermizis that are not found in traditional theories.
the Institute of Physics in 2016, researchers predicted for the first time the existence of a triple-simplified electron state, whose quasiparticles are triple-simplified and Fermizi.
this new fermi son is different from the four-part simple Dirac Fermizi, but also different from the two-part simple outer Fermi son, which should exist in a class of materials with tungsten carbide crystal structure. The
research team has since prepared a single crystal sample of phosphate tantalum in the tungsten carbide family, which was successfully analyzed in accordance with theoretical calculations during several months of experimental measurements by the Shanghai Light Source "Dream Line" and the Paul Schaller Institute in Switzerland.
This is the first time that a triple-simplified and Fermizi, which breaks the conventional classification, has been found in experiments, and the results are of great significance for scientists to explore the properties of elementary particles, understand the state of electronic topology, and then develop new electronic devices.
