• Resumen

  • Superconductivity holds great promise for delivering energy without the usual losses found in regular power lines due to heat and electrical resistance. It is notoriously tricky to achieve, but a new superconductor may help us better understand how such materials work -- and bring us closer to using them in everyday life. Superconductors transfer energy without resistance, but they generally only work at very low temperatures. Pablo Jarillo-Herrero at the Massachusetts Institute of Technology and his colleagues have made a superconductor that exhibits the same kind of resistance-free energy transfer as cuprates but is much less complicated. It switches easily between superconducting and insulating states, making it easier to study how superconductivity arises
