Researchers have proposed that a newly identified class of magnetic materials could extend the zero-resistance currents of superconductors to electron spins. Publishing their calculations in Physical Review X, Kyle Monkman and colleagues at the University of British Columbia propose how “altermagnets” could enable persistent spin currents to flow without dissipation. If confirmed experimentally, the effect […]

Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In a study published in Nature Physics, Qimiao Si’s group at Rice University, in collaboration with researchers at the Weizmann Institute […]

For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with no loss. Now, in a paper published in Nature, a team of Harvard physicists has reported new insights into why one promising superconductor has yielded […]
