Attosecond molecular physics in large (bio)molecules: A perspective on an unexplored landscape

The 2023 Nobel Prize in Physics recognized attosecond science and technology, which allows us to understand and control the properties of matter by accessing electron dy-namics at the Angstrom length scale. Attosecond science and technology are currently being applied to investigate all phases of matter and have garnered particular attention in the field of light-induced processes in molecules. After two decades of development, an attosecond perspective on molecular processes has become a tangible reality thanks to advanced experiments and theories. However, so far, this has only been applied to small model systems. This article discusses the current state of the field and explores how it could expand to include the study of complex structures, including large biomolecules.
