Date Time Share SLAC It’s an example of how surprising properties can spontaneously emerge in complex materials – a phenomenon scientists hope to harness for novel technologies. Creating a two-dimensional material, just a few atoms thick, is often an arduous process requiring sophisticated equipment. So scientists were surprised to see 2D puddles emerge inside a three-dimensional superconductor – a material that allows electrons to travel with 100% efficiency and zero resistance – with no prompting. Within those puddles, superconducting electrons acted as if they were confined inside an incredibly thin, sheet-like plane, a situation that requires them to somehow cross over to another dimension, where different rules of quantum physics apply.
