Optically driven yttrium barium copper oxide shows puzzling magnetic signals at high temps. New theory ties this to a flux-Floquet instability, not light-induce

Optically driven yttrium barium copper oxide shows puzzling magnetic signals at high temps. New theory ties this to a flux-Floquet instability, not light-induced superconductivity — evidence for preformed Cooper pairs in the pseudogap phase. Read more: [↧](https://t.co/u…
