In 2010, scientists at the National St. Petersburg University and the Russian Quantum Center jointly proposed a new theory for the preparation of high-temperature superconducting materials using laser radiation.
According to the news from the Russian news network, the research team of the Max Planck Institute for Physical Structure and Dynamics in Germany recently verified the correctness of the theory, and further improved the theory, and recently developed close to room temperature. Superconducting material.
According to this theory, when a green laser pointer is used to irradiate a material, the interaction of the laser beam with the substance can generate electromagnetically polarized quasi-particles inside the material, and the cyan condensed state formed by the quasi-particles can make the material have a high temperature super Inductive. Aluminum metal is superconducting, but due to the oscillation of its crystal lattice, the electrons are coupled into a Cooper pair, so its superconductivity can only be manifested at ultra-low temperature. If this superconducting metal is added to the selected material, the laser Radiation treatment tends to form a unique structure inside the material, the material is converted into a superconductor, and superconductivity can be achieved at high temperatures, with temperatures approaching room temperature.
When the resistance value drops to zero, the material is superconducting. The superconducting state not only enables lossless transmission of electrical energy, but also establishes a strong magnetic field for applications such as hadron colliders and magnetic levitation vehicles. The purpose of many years of research by researchers in the field of superconductivity is to increase the temperature of superconductors, and the green laser pointer materials to be used must meet the requirements of technical indicators such as low cost, non-toxicity and toughness. At present, relevant results have been published in the scientific journal of Physical Review Letters.
