Schematic diagram
The electron-formed Cooper pair maintains a stable superconducting state at high temperatures by passing between the pairs of electrons formed by the concealed composite fermions.
The University of Tokyo, Japan and Paris South University (Paris University of Paris) announced on January 29, 2016 that a new mechanism for the superconductivity of copper oxide high-temperature superconductors at high temperatures has been discovered. Through numerical simulations, the two universities discovered the electronic motion that cannot be explained by the original theory and determined that this abnormal motion is the direct cause of HTS. This achievement will indicate a new direction for the design of high-temperature superconductors.
Since the discovery of copper oxides in high-temperature superconductors in 1986, many studies have been conducted in the industry, but there are still many mysteries about the mechanism of high-temperature superconductivity. Past research has found that copper-oxide superconductors, like other superconductors, consist of two pairs of electrons (Cooper and electrons). Many theories speculate that this is due to the attraction of two electrons by an even number of Electron-forming particles (a kind of boson) act as mediators.
This time, the two universities conducted numerical simulations based on the latest theoretical theory of the interaction between electrons for a theoretical model believed to be able to express the electronic state of copper oxides. As a result, they discovered an abnormal movement phenomenon that can be performed in the metallic state. Electrons that feel particularly strong in their interactions do not feel the interaction at the instant that they become superconducting. This is inexplicable for the original theory of gravitational attraction of the glass.
Thus, the two universities assume that there is a fermion (composite fermion) formed by an odd number of electrons instead of an even number of electrons to verify the electronic motion at this time, and the results surprisingly reproduce the numerical simulation results. Composite fermions are not inherently elementary particles like electrons, but are products formed by multiple electrons in solids under the action of strong mutual exclusion between electrons. In addition, it is also found that Cooper pairs electrons passing between complex fermion states, making the superconducting state stable at high temperatures.
The two universities are considering the implementation of an observable composite fermion experiment, confirming the prediction of the existence of complex fermions through experiments, and elucidating the mechanism of iron-based superconductors in the high-temperature superconducting state after copper oxides.
