Theorists created a gravitational model that is mathematically analogous to one for a standard superconducting device, extending the ways that the tools of general relativity can lead to insights into condensed matter physics.
Although theoretical approaches to modeling “strange metals,” such as the cuprate superconductors, originate from apparently different sources, research now suggests they flow toward a single universal model.
Results from string theory, generalizing the anti-de Sitter/conformal field theory correspondence, may offer a fresh set of mathematical tools for understanding some kinds of phase transitions that occur in cold atomic systems.

Extra spatial dimensions–beyond the three we know–could alter Newton’s inverse-square law of gravity at short distances. But new measurements show that Newton is correct down to at least 200 micrometers.
