The group's work has been recently published in Nature Physics! The article entitled: Real-space imaging of the electron-pair density hole in molecular Auger–Meitner decay describes the work that Mats, Andres has been working on for the last little while. It showcases the state-of-the-art experimental and theoretical techniques in ultra-fast X-ray imaging. Thank you to our collaborators at Brown (Peter Weber), Tübingen (Elke Fasshauer), and SLAC. Congratulations to Mats, Andres, and all involved!
