These copper-oxide materials are most famous for being high-temperature superconductors, meaning they conduct electricity with zero resistance at temperatures far above that of normal superconductors. Strange metal behavior was first discovered around 30 years ago in a class of materials called cuprates. It needs to be more fundamental than that."
"What this says is that any theory to explain strange metal behavior can't be specific to either type of particle. "We have these two fundamentally different types of particles whose behaviors converge around a mystery," said Jim Valles, a professor of physics at Brown and the study's corresponding author. This is the first time strange metal behavior has been seen in a bosonic system, and researchers are hopeful that the discovery might be helpful in finding an explanation for how strange metals work - something that has eluded scientists for decades. While electrons belong to a class of particles called fermions, Cooper pairs act as bosons, which follow very different rules from fermions. In research published in the journal Nature, the team found strange metal behavior in a material in which electrical charge is carried not by electrons, but by more "wave-like" entities called Cooper pairs. But for a more detailed study, we may need another mission to fully understand what is happening on the Sun.Įarlier we reported on how a powerful solar flare disabled radio in Africa and the Middle East.Now, a research team co-led by a Brown University physicist has added a new discovery to the strange metal mix. Although the current Solar Orbiter mission of the European Space Agency may provide some insight. Unfortunately, it is not yet possible to study the polar region directly, since scientists can observe the Sun only from the plane of the ecliptic or the orbit of planets. Why does it only move toward the pole one time and then disappears and then comes back, magically, three or four years later in exactly the same region?,” said McIntosh.
“Once every solar cycle, it forms at the 55 degree latitude and it starts to march up to the solar poles. But they don’t know what the exact reason for its formation is. Scientists believe that this phenomenon is associated with a change in the magnetic field of the Sun and believe that the polar region is very important in creating a magnetic field.
But even if scientists have observed such “fences” in the solar plasma, it has never led to the formation of a polar vortex, as recently observed. McIntosh described the northern vortex as a “living enclosure in the solar plasma” that appeared every 11 years in exactly the same place around the polar corona of the Sun. During this period, things such as solar radiation, the release of solar material, sunspots and solar flares fluctuate. Solar cycles are periodic 11-year changes in the activity of the Sun. But he notes that such strange events usually occur at the latitude of 55° of the Sun once per solar cycle. Scott McIntosh, a physicist and deputy director of the National Center for Atmospheric Research in Boulder, Colorado, said he had never seen such a vortex. Implications for understanding the Sun’s atmospheric dynamics above 55° here cannot be overstated! /1SKhunaXvP Talk about Polar Vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star.

Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star. Animation of a “breakaway” prominence in the Sun, which began to orbit the North pole Space forecaster Tamitha Skov posted a video of this mysterious process on Twitter. Scientists can’t explain this strange phenomenon yet. This phenomenon was like a giant polar vortex. Last week, part of the prominence on the Sun “broke off” and began to orbit the north pole of the Sun.
