In STM with a CO tip, molecular orbital densities look totally different at different tip heigths. Here is why and how to account for it. Teaser: It's NOT due to different decay constants of s- and p- wavefunctions, as one might have guessed (!) pubs.acs.org/doi/10.1021/ac…

Das Projekt CarboQuant am nanotech@surfaces Lab der Empa erforscht quantenphysikalische Phänomene mittels Kohlenstoff-Nanostrukturen. Nun gelang ihm ein Durchbruch: Es hat eines der wichtigsten theoretischen Quantenmodelle exakt nachgebaut und getestet. wernersiemens-stiftung.ch/detail/spin-ke…

In the CarboQuant project at nanotech@surfaces Lab researchers are using carbon nanostructures to study quantum physical phenomena. They’ve now achieved a breakthrough by precisely constructing and testing one of the most important theoretical quantum models. wernersiemens-stiftung.ch/en/news/detail…

Empa has opened the CarboQuant Lab, a cutting-edge hub exploring quantum effects in carbon. Supported by the Werner Siemens-Stiftung and the Swiss National Science Foundation , CarboQuant aims to create a materials platform for carbon-based quantum technologies.
