Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor.

The research promises to enhance our understanding of quantum physics in solids in general and also propel the study of quantum condensed matter physics and…

Princeton physicists developed a new experimental approach that precisely detects quantum mechanical fluctuations on the verge of a phase transition of a two-dimensional superconductor. The results uncover a new type of quantum phase transition that cannot be explained by the established theories used to describe phase transitions in superconductors. This research promises to propel the study of quantum condensed matter and superconductivity in new directions.
