Africa-Press – Sierra-Leone. <\/strong><\/span>So-called “strange metals” do not behave in ways typical to other metals when they are heated or cooled, deviating from the usual rules of physics. Scientists have discovered a new “strange metal” with a behaviour they do not seem to understand. The moment occurred when looking into bosonic systems, where such behaviour had not been spotted before.<\/p>\n

The new research was published in Nature on Wednesday, titled “Signatures of a strange metal in a bosonic system”. The scientists discovered a never-before-seen type of metal behaviour in the system, where an electrical charge is not carried by electrons, as usual, but by so-called Cooper pairs.<\/p>\n

Cooper pairs are bosons \u2014 particular kinds of subatomic particles. Electrons are fermions, another kind of such particles. The new research could open the door to solving a mystery that has been troubling scientists for almost three decades, since cuprates \u2014 a class of materials that tend to behave in ways different to other metals \u2014 were discovered.<\/p>\n

These “strange materials” do not appear to display the same characteristics as other other metals when they are heated. Normally, their resistance goes up until the point when it becomes constant. Cuprates, however, do not follow these rules, and scientists are still struggling to figure out why.<\/p>\n

Seeking to better understand the behaviour of the “strange metal”, scientists used a cuprate material with tiny holes in it to produce the Cooper pairs, cooled it down, and observed changes in its conductance. They ended up seeing that it behaved in ways similar to fermionic strange metals \u2014 which, however, provides little progress in understanding where this behaviour comes from.<\/p>\n
