Researchers have identified a mechanism, called “oscillating superconductivity”, that could revolutionize the way we use energy. This mechanism allows certain materials to become superconductors at temperatures much higher than those usually required.
Currently, extreme cold is required to achieve superconductivity, as shown in this image of a magnet floating above of a superconductor.

The phenomenon of superconductivity comes from the interaction between electrons within a material (A material is a material of natural or artificial origin that man shapes…). At low temperature (Temperature is a physical quantity measured using a thermometer and…), electrons cause ripples in matter (Matter is the substance that makes up any body having a tangible reality. Its. ..), pushing the atomic nuclei closer together. This movement causes a bond between two electrons, forming (In intonation, changes in fundamental frequency are perceived as variations of…) what is called a “pair (A set E is said to be a pair when it is formed of two distinct elements…) of Cooper”. These pairs follow different quantum laws and can coexist at the same point in space without loss of energy (In common sense, energy designates everything that allows work to be done, manufacture of…).
The first superconductor was discovered in 1911 by the Dutch physicist Heike Kamerlingh Onnes (Heike Kamerlingh Onnes (September 21, 1853 in Groningen, Netherlands -…). But it was not until 1986 that physicists discovered materials (A material is a material of natural or artificial origin that man shapes to make…), called cuprates, capable of becoming superconductors at less extreme temperatures. However, the objective of superconductivity at room temperature always seems out of reach.
According to Luiz Santos, assistant professor of physics at Emory University, the shortcomings in the design of room-temperature superconductors are due in part to a misunderstanding of the necessary theoretical conditions. The recent study focused on specific forms of high temperature superconductivity where the Cooper pairs are organized in waves (A wave is the propagation of a disturbance producing in its passage a reversible variation…) of density charge (Electrical charge density refers to the quantity of electric charge…). Their emergence would probably be related to a concept called Van Hove’s “singularity (Generally speaking, the word singularity describes the singularity of something or…)”, where electrons at different speeds can exist at the same energy, facilitating their twinning.
Although this study is still theoretical, it opens the way to further research. Santos concludes by emphasizing that any discovery has immense potential for application, even if it is not immediately obvious.
