Roadmap on Attosecond Science
Rocio Borrego Varillas, Pierre Agostini, Fernando Ardana-Lamas +108
Twenty-five years have passed since the first experimental demonstration of attosecond pulses, marking the advent of our ability to resolve and control electron motion in real time…
Reply to "Comment on Brilliant source of 19.2 attosecond soft X-ray pulses below the atomic unit of time" by Han (arXiv:2510.17949)
Fernando Ardana-Lamas, Seth L. Cousin, Juliette Lignieres +1
We recently reported a refine analysis of a previously conducted soft X-ray (SXR) attosecond streaking measurement [1], employing the Variational Phase Gradient Temporal Analysis (…
Brilliant source of 19.2 attosecond soft X-ray pulses below the atomic unit of time
Fernando Ardana-Lamas, Seth L. Cousin, Juliette Lignieres +1
Electronic correlations occur on attosecond timescales, dictating how chemical bonds form, energy flows, and materials respond to light. Capturing such many-body processes requires…
Few-femtosecond electronic and structural rearrangements of CH driven by the Jahn-Teller effect
Kristina S. Zinchenko, Fernando Ardana-Lamas, Valentina Utrio Lanfaloni +5
The Jahn-Teller effect (JTE) is central to the understanding of the physical and chemical properties of a broad variety of molecules and materials. Whereas the manifestations of th…
