Physicists from Princeton have identified a sudden shift in quantum behavior during experiments with a three-atom-thin insulator, demonstrating its ability to transition effortlessly into a superconductor.
At low enough temperatures, certain metals lose their electrical resistance and they conduct electricity without loss. This effect of superconductivity is known for more than hundred years and is .

Superconductors have intrigued physicists for decades. But these materials, which allow the perfect, lossless flow of electrons, usually only exhibit this quantum-mechanical peculiarity at tempera .
The promise of a material that could revolutionise the way we use electricity captured imaginations on social media, which also helped researchers quickly determine that LK-99 wasn't what it seemed
