Exotic New Superconductors Delight and Confound

Three new types of superconductors were discovered this year, challenging our understanding of this phenomenon. These two-dimensional materials, like graphene, exhibit unprecedented flexibility, switching between insulating, conducting, and superconducting states with simple adjustments. One even defies expectations by strengthening in a magnetic field. These discoveries deepen the mystery of superconductivity while offering hope for room-temperature superconductors, potentially revolutionizing energy and transportation.
