From quantum gravity to strange metals
What does a quantum theory of gravity have in common with electrons in a ’strange’ metal? At first sight: not much, but this week in Nature a Dutch NWO consortium, including researchers Jake Ayres, Maarten Berben and Nigel Hussey (Radboud University), Jan Zaanen (Leiden University) and Erik van Heumen (University of Amsterdam) reports on new experimental findings that may point towards such a link after all.
Near-field imaging of metal insulator transitions
Scattering type scanning near-field optical spectroscopy enables us to image local variations in the optical properties of materials with nanometer scale resolution.
