The idea of levitating off the ground has captivated human imagination, and quantum levitation demonstrates that specially-made materials can float indefinitely above magnets under the right conditions.
Bulk superconductivity near 40 K in hole-doped SmNiO2 at ambient pressure - Nature
The discovery of superconductivity in the Ba-La-Cu-O system marked a breakthrough, inspiring extensive explorations in oxide-based layered superconductors to identify electron pairing with higher critical temperatures.
New Superconductive Materials Have Just Been Discovered
The recent spate of discoveries has both compounded the mystery of superconductivity and heightened the optimism. "It seems to be, in materials, that superconductivity is everywhere," said Matthew Yankowitz.
