Polar molecules feature much stronger dipole moments than magnetic atoms—but what frontiers can we realistically explore with molecular Bose-Einstein condensates? 👉 arxiv.org/abs/2512.14511 We review this open question and the exciting possibilities in the field, from few- to many-body physics ...

Notably, this makes it a double-double of 🇪🇺 #ERC grants for the Atominstitut this year — 🏅Andreas Schindewolf and 🏅Uroš Delić received an #ERCStG, while 🏅Philipp Haslinger and 🏅I received an #ERCCoG — and a double-triple for the #Physics Department at @tuwien.at

Freude, schöner Götterfunken! 🇪🇺 I’m thrilled to share that my research group will soon be supported by an ERC Consolidator Grant from the @ERC — my third ERC grant! 🎉 In this project, we will be working towards precision measurements of parity violation using cold #molecules.

In June, I participated in an exciting workshop on #Ultracold Molecules, organized by @michaltomza.bsky.social and Simon Cornish at the University of Warsaw. The recordings of the talks are now available on the Youtube channel of the Centre for AMO Physics (🔗 www.youtube.com/@CAMOP_UW/vi...).

Glad to share the news of our newly funded Special Research Area (SFB) of the @fwf-at.bsky.social. QNNECT will be a collaborative project on neutral-atom hashtag#quantum systems with high connectivity — spanning Rydberg atoms, atoms in cavities, magnetic atoms, and polar molecules.

You got yourself complex #molecules to laser cool and want to find the best laser configuration for cooling? Use our #python package MoleCool: arxiv.org/abs/2510.16203 As a bonus example: how to (or maybe not to) laser cool radioactive radium monofluoride molecules!

🚀 Great success! Three 🇪🇺 #ERC Starting Grants this year go to @tuwien.at — including one for Andreas Schindewolf from my group! 🎉 Proud moment for our team and a big congratulations to Andreas and all other awardees! @erc.europa.eu | #VCQ | Quantum Science Austria | #quantum #ERCStartingGrant

Recently had the pleasure of giving an invited talk at the ESNT Workshop on "Theoretical and experimental developments for symmetry-violating nuclear properties" at @cea.fr Saclay! @tuwien.at | @fwf-at.bsky.social | #quantum

A new PhD graduate from the Cold Molecules group! Huge congratulations to Felix Kogel for successfully defending his PhD with the highest distinction! Felix's doctoral hat includes an interactive replica of the #lasercooling experiment for new types of #precisionmeasurements described in his thesis!

Fantastic workshop on Ultracold Molecules at Warsaw University, organized by Simon Cornish and @michaltomza.bsky.social! Greatly enjoyed joining as a speaker and panelist - amazing talks & discussions, and a real sense that #molecules are one of the most exciting areas of quantum science today!

My timelines are usually filled with pictures of either #quantum physics or mountains. What a unique opportunity to combine them both! Approaching @apsphysics.bsky.social's #DAMOP2025 meeting in Portland, flying in right over the crater rim of Mt. St. Helens, with Mt. Adams in the background.

Barium charge radii in molecules do the (odd-even) twist: High-resolution spectroscopy of barium monofluoride that benchmarks theory, reveals nuclear properties and prepares the molecules for more efficient laser cooling along the way.

Ich habe kürzlich zu zwei Artikeln im neuen Sammelband "Physik: Erkenntnisse und Perspektiven" der Deutsche Physikalische Gesellschaft beigetragen. Darin fassen über 200 Physikerinnen und Physiker gemeinsam viele faszinierenden Aspekte der modernen #Physik zusammen.

I recently had the honor of delivering my official inaugural lecture as a professor at @tuwien.at. It was a fantastic opportunity to share my group’s research in #quantum science and technology and connect with colleagues, students, and friends. I'm excited for what lies ahead!

New crystal morphologies for #dipolar quantum matter Dipolar atoms and molecules naturally self-assemble into droplet crystals, but did you know these #droplets can further transition into flawless monolayer crystals when interactions become strong enough? See here: arxiv.org/abs/2504.02682

Two levels are great for qubits, but molecules can take it to the next level—currently 112 of them, to be exact. We've controlled this complexity to realize laser cooling of previously intractable 137BaF molecules, preparing them for sensitive tests of the Standard Model. arxiv.org/abs/2501.16095

Less is more: how to optimize the laser light for the laser cooling of complex molecules. arxiv.org/abs/2501.10725 First new preprint of 2025! #coldmolecules #quantum #lessismore #serrodynes

Enjoying a morning walk to teach my lecture at TU Wien's Master’s program in #Quantum Information Science and Technology. No, this is not the lecture hall - but it's only a short walk away. Join us next semester! For details, see here: informatics.tuwien.ac.at/master/quant... #fuTUrefit

Together with Tanya Zelevinsky, Sebastian Will and Tijs Karman we are organizing a summer workshop on Cold #Molecules for Fundamental Physics and Many-Body #Quantum Science at Aspen Center For Physics. Join us to learn about and contribute to the latest developments in this exciting field!

Great resource for finding quantum people here!

Last week I attended the #CCMI2024 conference organized ISTAustria by Misha Lemeshko and Katrin Erath-Dulitz. Now Misha has made a video about it ... www.youtube.com/watch?v=T7kP... #science #physics #chemistry #coldmolecules

A very pleasant surprise: My final lecture course held at @unistuttgart.bsky.social last summer term has been awarded with a teaching award for the best elective course in #physics. Great to receive this #award the second time in a row! #quantum | #teaching | #wequantum

Had a great time at University of Cambridge for the ICAP satellite conference on Cold Atoms and #Molecules for Fundamental Physics. manybody.phy.cam.ac.uk/ICAPSatellite Thanks to Tiffany Harte and Ulrich Schneider for a fabulous workshop!

New preprint with colleagues from Barcelona and Nijmegen, providing insights into self-bound #molecular #droplets in the strongly dipolar regime! arxiv.org/abs/2407.09391 Will #quantum Monte Carlo simulations play a similar role for molecular quantum gases as eGPE did for magnetic atoms?

New paper: Bring on the rare molecular isotopologues! For atoms, laser cooling is frequently used to cool different isotopes, or even collect rare isotopes. In our latest paper, we demonstrate such selective cooling for molecules for the first time! arxiv.org/abs/2406.01569

The big BaF chill: heavy barium monofluoride molecules are getting cold! See our latest preprint for a new approach to implement #laser #cooling for this and other complex molecular species. #coldmolecules #quantum arxiv.org/abs/2405.09427

It was a pleasure to represent TU Wien and the #Atominstitut at the inauguration of the new #COSINUS experiment at Gran Sasso National Lab. Great achievement by Karoline Schaeffner, Florian Reindl and their collaboration - exciting #darkmatter science ahead for them! lnkd.in/gawMeeXa
