Quantum Electron Wavepacket Spectroscopy

Can we shape an electron wavepacket in space and time? Can we tailor it to probe material properties that are currently inaccessible? Recent work has shown that high-energy electrons (80-200 keV) interacting with strong light fields can absorb or release quantized energy packets equal to the photon energy. This dresses the electron into a superposition state composed of a spectrum of energy-loss and -gain sidebands. Here we exploit this Photon-Induced Near-field Electron Microscopy (PINEM) effect in order to create a revolutionary new method of tailoring the spatial and temporal distribution of electron wavepackets at will. Building on my strong expertise in the field of…
