We have discovered an entirely unforeseen quantum-mechanical contrast mechanism that finally enables all-optical microscopy to achieve atomic resolution while retaining subcycle temporal precision. This new concept allows us to directly trace the quantum flow of electrons on their intrinsic length and time scales.
The results obtained in a close collaboration with the group of Jan Wilhelm (University of Regensburg) have appeared in Nature.
