Researchers at The Ohio State University, in collaboration with scientists around the world, have made a discovery that could provide new insights into how superconductors might move energy more efficiently to power homes, industries and vehicles. [34] Now, new experiments conducted at Princeton give hints at how this material-known as magic-angle twisted graphene-gives rise to superconductivity. [33] Finally, we can look at a key property of superconductivity that previously couldn't be seen." [32] Researchers from Tokyo Metropolitan University have found that crystals of a recently discovered superconducting material, a layered bismuth chalcogenide with a four-fold symmetric structure, shows only twofold symmetry in its superconductivity. [31] Russian physicist Viktor Lakhno from Keldysh Institute of Applied Mathematics, RAS considers symmetrical bipolarons as a basis of high-temperature superconductivity. [30] Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have shown that copper-based superconductors, or cuprates-the first class of materials found to carry electricity with no loss at relatively high temperatures-contain fluctuating stripes of electron charge and spin that meander like rivulets over rough ground. [29] Researchers from Google and the University of California Santa Barbara have taken an important step towards the goal of building a large-scale quantum computer. [28] Physicists have shown that superconducting circuits-circuits that have zero electrical resistance-can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum computers and other devices with improved efficiencies. [27]
