STOCKHOLM: An international team of scientists has discovered a new state of matter called “electron quadruplet” after long research, which occurs at very low temperatures and contains four electrons together.
Experiments at the KTH Royal Institute of Technology, Sweden, have revealed this new state of matter and now experts are trying to find out more about its properties.
It should be noted that particles with the same charge push each other away, that is, they “repel”.
Electrons have a negative charge, so when two electrons are brought close to each other, the repulsive force between them increases.
This is why it is considered extremely difficult for two or more electrons to be very close to each other.
However, “superconductors”, ie substances through which electricity passes without any resistance, have been observed to have electrons in the form of pairs, which is unusual. This process takes place at extremely low temperatures.
About 20 years ago today, Professor Igor Babayev, a scientist from TH Sweden, predicted the coexistence of four electrons, the “electron quadruplets”, and in 2013 published a research paper on the subject. Was
This prediction was so unusual that the majority of physicists refused to accept it.
In 2018, for the first time, Vadim Greenenko and his colleagues at the University of Technology in Dresden, Germany, made some observations that were in line with the predictions of electron quadruplets.
For three more years, hundreds of experiments and observations were made on superconductors of extremely cold temperatures in various laboratories around the world to confirm this possible discovery, the combined results of which have been published online in the latest issue of Nature Physics.
Professor Igor Babayev says that there are some new and unusual features in electron quadruplets that we are still trying to fully understand.
Currently, this is a very early discovery that will improve the superconductor material once more information is available.
