Carolina Parra (center), who as a Stanford postdoc carried out the experiments that led to the visualization of these intriguing results, now heads a lab at the Federico Santa María Technical University in Valparaíso, Chile, focusing on interdisciplinary studies of nanoscale biological materials. She recently won a grant to acquire and operate the first-ever low-temperature scanning tunneling microscope in South America, which she plans to use to continue this line of research.

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.
