Watching electron motion in solids
March 26, 2025 Studying the extremely fast movements of electrons much easier than previously possible - as our SFB physicists Daniel Timmer, Antonietta de Sio and Christoph Lienau and co-workers report in their article "Phase-cycling and double-quantum two-dimensional electronic spectroscopy using a common-path birefringent interferometer". The new method allows for a variety of new experimental possibilities for spectroscopy and microscopy. The 2D spectroscopy is, e.g., ideally suited for probing coherent dynamics and charge transfer processes in erCry4 proteins (image by M. Gittinger).
