ATTO Group @ ETH Zürich

Our group develops experimental methods for measuring and controlling electronic dynamics of molecules on the attosecond time scale.

New publication! 🚀In our latest work, we demonstrate a quantum-mechanically complete technique to retrieve the amplitude and phase of photoelectron wave packets in the presence of Fano resonances, where quantum interference complicates the dynamics. https://t.co/f8elJOkUN3

New review alert! 🔍🚨 In our latest review, published in @NatRevChem, in collaboration with Jean-Pierre Wolf from the University of Geneva, we explore how extreme-ultraviolet to soft-X-ray pulses are transforming the ultrafast spectroscopy of liquids: https://t.co/SkfUUXQkcG

New paper alert! 🚨 Check out our latest collaborative effort to unravel the dephasing of the electron dynamics created at conical intersections with single-photon excitation in aqueous media: https://t.co/9ayZyNrj6g

Congratulations to Anne L'Huillier, Pierre Agostini and Ferenc Krausz for being awarded the #NobelPrize. We are very honoured to have the Nobel committee feature our work on liquid water as an application of the attosecond technology these brilliant scientists have developed.

[Hans Jakob Wörner @HansJakobWorner]

Congratulations to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for winning the 2023 #NobelPrize in Physics. They opened a vibrant field of research that is creating fundamentally new knowledge and future technologies.

5 years ago our group generated the first EUV harmonics in liquids, promising a novel powerful probe of liquids' electronic properties. Our newest publication delivers; showing the sensitivity of the harmonic spectrum to the elusive electron mean free path https://t.co/JDnh4qn79E

Congratulations to Sum Chung Leung on being awarded the 'Best Student Poster Prize' at #ATTO9 last week! Together with Dr. Meng Han he has performed attosecond ionisation delay measurements across the ionisation threshold with surprising results! Stay tuned for more!#attoscience

[D-CHAB @ETH_DCHAB]

Scientists led by Hans-Jakob Wörner @ETH_en @unige_en developed a method for observing chemical reactions in liquids at extremely high temporal resolution. The insights further, e.g., our understanding of how life might have begun.

Congratulations to Dr. Xiaochun Gong on being awarded the 2023 @EuroPhysSoc #QEOD Fresnel prize for developing attosecond coincidence metrology for ultrafast photonics! We are very proud to have had you be part of the team! https://t.co/vhQbel06ru

Our warmest congratulations to our group leader, Prof. Hans Jakob Wörner for his promotion to full professor and on the occasion of his birthday. With all the sugar in this cake, lets hope it doesn't trigger any non-aDIABETIC dynamics.

Chemical reactions mostly happen in the liquid phase but the influence of solvation remains poorly known. Comparing liquid and gas phase photoisomerisation, we show that although the process is slower in liquids, its vibrational dynamics remain coherent. https://t.co/pTub8PBqml

[ATTO Group @ ETH Zürich @atto_ethz]

Charge migration, a form of coherent electronic motion, is the fastest known chemical process. We investigate the effect molecular vibrations have on electronic coherence finding it long-lived enough to allow for control of chemical reactions with light https://t.co/pQLqPzT3OP

In previous work our group compared attosecond electron dynamics of liquid and gaseous water. Our newest publication indicates the origin is a fundamentally quantum effect - the delocalisation of electrons across multiple water molecules: https://t.co/lKwy3hqkeb

[ATTO Group @ ETH Zürich @atto_ethz]

Chirality is a property exhibited by most biologically-active molecules. It’s the difference between something smelling piny, citrusy or even being toxic. Our group has now managed to measure ultrafast chirality changes during chemical reactions: https://t.co/fUTKmiLwyx

[ATTO Group @ ETH Zürich @atto_ethz]

By developing electron-electron coincidence spectroscopy with liquid microjets, our group has been able to directly observe Intermolecular Coulombic Decay (ICD) in liquid water, a process known to be involved in biological radiation damage. Read more here: https://t.co/qpzkaNilMY

Molecules are anisotropic objects, which results in anisotropies in the time it takes electrons to escape from them. In our latest work, we managed to observe and understand this effect by following an electron on its escape from a shape resonance in CF4 https://t.co/9vrlT92bA5
