Research and career — proposed additions

In 2007, Biegert joined ICFO in Barcelona as an ICREA Research Professor, heading the Attoscience and Ultrafast Optics group.

His research focuses on the dynamics of electrons and atomic nuclei on attosecond timescales and nanometer length scales, using high-power laser systems spanning the mid-infrared to soft X-ray spectral range. Topics include strong-field physics, high-harmonic generation, ultrafast spectroscopy of quantum materials, and optical control of material properties. His group developed ultrafast mid-infrared laser systems and frequency combs enabling strong-field experiments at high repetition rates, and extended strong-field physics to longer wavelengths through ponderomotively-scaled attoscience. [ cite: Opt. Express 17, 3587 (2009); Nat. Photon. 9, 721 (2015)]

In 2015, the group generated isolated attosecond pulses in the soft X-ray water-window spectral region. [cite: Nat. Commun. 6, 6611 (2015)]

In 2016, Biegert's team, in collaboration with Kansas State University and other partners, reported a direct imaging of bond breaking in a molecule using laser-induced electron diffraction with attosecond and picometer resolution. [cite: Science 354, 308 (2016)]

In 2019, the group directly imaged the bending and stretching of a carbon disulfide (CS₂) molecule in real time, observing structural changes driven by the Renner–Teller effect. [cite: PNAS 116, 8173 (2019)]

The group subsequently introduced attosecond core-level spectroscopy as a method for following energy transfer among electrons, phonons, and the crystal lattice in real time, applying it to ultrafast phase transitions in semimetals and molecular systems. [cite: Nat. Commun. 7, 11493 (2016); Phys. Rev. X 11, 041060 (2021); Nat. Photon. 18, 731 (2024)] In 2022, the group reported optical detection of quantum phases in superconductors using high-harmonic spectroscopy. [cite: PNAS 119, e2207766119 (2022)]

In 2024, the group demonstrated optical control of valley topology in bulk materials, showing that valley polarization can be induced without requiring atomically thin samples. [ cite: Nature 628, 746 (2024)]

Since 2019, Biegert has been a scientific guest at the Fritz Haber Institute of the Max Planck Society in Berlin. He served as Executive Director of Laserlab-Europe from 2021 to 2023 and has served on the Board of Directors of Optica and on advisory boards for international research infrastructures.

I am happy to provide draft wikitext for any or all of the above if that would be helpful to reviewing editors. Thank you for your time.

• Why it should be changed:

There are some changes that are needed as the current information is not correct or incomplete (affiliation, date of birth, and awards).

The section of Research has been edited to make it easier for readers, and I have added extra references of the papers.

1. Please provide wiki text, I won't (and neither will others) generate it for you.
2. The education and awards section are OK, you can go ahead with those.
3. Why not APS Fellow in awards? Those should be a separate section towards the end.
4. The Research section you provided is a list of major papers. That is very resume-like, not the best encyclopedic form. We do not want a CV, we want to know what he has worked on with a few (~<10) top papers.

Ping he with a revised version. Ldm1954 (talk) 13:38, 31 July 2026 (UTC)
