Next generation of radio-frequency scanning tunnelling microscopy – GINET2_0

Submission summary

In the field of atomic physics, atomic spectroscopy techniques have allowed probing low energy magnetic or electronic excitations of single atoms since decades. In condensed matter systems, where atoms interact strongly with their environment, lifetimes of excited states are short, thus only large systems were investigated with magnetic resonance techniques. With the development of quantum computing, condensed matter physics faces the challenge of sensing low energy excitations at the single atom limit. Thanks to tremendous research efforts, the sensitivity of magnetic resonance techniques is rapidly improving. The recent combination of scanning tunnelling microscopy with radio-frequency (RF-STM) opens a new era by giving access to magnetic excitations in the neV-range at the single atom level. We propose here to go further by developing new RF-STM techniques which will enable magnetic imaging of buried objects with a sub-nm resolution, as well as sensing electronic excitations.
