Our paper on highly-efficient GW calculations of bandstructures of 2D materials has been accepted in Phys. Rev. B. Nice collab with M. Camarasa-Gómez, A. S. Hehn, J. Wilhelm @wilhelm_cpm Check the preprint: arxiv.org/abs/2507.18411

Excited to share that our latest research has been published in @NaturePhotonics! Huge thanks to my amazing colleagues from @UniJena, @uni_regensburg, @IESL_FORTH, and @VSCHT for their collaboration. Check out our article here: nature.com/articles/s4156…

Ever imagined capturing chemical reactions with atomic resolution on video?🧬⌬🎥 We take a step closer to this vision with near-field optical tunneling emission (NOTE) microscopy💥nature.com/articles/s4158… @Huber_Group NOTE mechanism validated by real-time TDDFT💻! @CP2Kproject

Some work from my time in Regensburg, in the @Huber_Group. We worked out how to measure the coherent emission from tunnelling electrons, this lets us do ultrafast optical microscopy now at the atomic scale! nature.com/articles/s4158…

We have discovered a quantum-mechanical contrast mechanism that enables all-optical microscopy to achieve atomic resolution while retaining subcycle precision. This new concept allows us to trace electrons on their intrinsic length and time scales. nature.com/articles/s4158…

We develop ultrafast lightwave-driven scanning tunnelling spectroscopy to investigate how the spin-orbit-split energy levels of an isolated Se vacancy within a WSe2 monolayer shift under phonon displacement. Read the full story in @NaturePhotonics. nature.com/articles/s4156…

Quantum dance to the beat of a drum: physicists at the University of Regensburg choreograph the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second. Read the full story in @NaturePhotonics. nature.com/articles/s4156…

Everything open-source & we tried to be as user-friendly as possible 😇 Howto with exemplary inputs available here: #gw-for-2d-materials-example-monolayer-mos2" target="_blank" rel="nofollow noopener">manual.cp2k.org/trunk/methods/…

Together with @UMengineering, we realized a stopwatch for delocalized Bloch electrons in crystals that achieves attosecond precision. This way, many-body correlations can be directly measured. Our results were published in @Nature. nature.com/articles/s4158…
