The capability to capture electronic and atomic motions at their natural length (Ångstrom-scale) and time-scales (attoseconds to femtoseconds) is a long-standing goal in modern science. In my talk, I will show you how electron dynamics in molecules can be locally probed with angstrom-scale spatial resolution and 300 attosecond temporal resolution simultaneously, at the single orbital-level with the help of a scanning tunnelling microscope (STM), defying the previously established fundamental space-time limits [1-4]. Atomic motions in a single molecule can be directly imaged by realizing coherent anti-Stokes Raman spectroscopy in an STM [5-6]. These recent developments pave the way towards direct real space-time imaging of chemical reactions and phase transformations in two-dimensional materials.
