See our new paper on a first clean, pristine cuprate in Mott insulating state! nature.com/articles/s4324… @NaturePortfolio @CommsMaterials @IzabelaBialo et al.,

We didn’t brag right away, but we’re catching up! 😄 Congratulations to Julia Küspert for winning the Best PhD Thesis Award in Experimental Physics, supported by Zurich Instruments! 🏆✨ Julia is our former PhD student, currently based in @esrfsynchrotron 💪

We are at the Superstripes conference in Erice, in the famous Ettore Majorana Foundation! It is a privilege to give a presentation here ☺️ Invited talk: Iza

We look back fondly on the SPS-ÖPG meeting in beautiful Vienna😊 See you next year!

This month we welcome a new team member, an exchange student from @CUHKofficial in Hong Kong, Alris Dai! Alris works on improving algorithms for processing XRD and RIXS data💪

We are at SCES 2025 ! Two contributed talks checked ✅ Best greetings from Montréal from Iza & Leo 👋

‼️New paper in @NaturePortfolio @CommsPhys ‼️ The story of the spin-orbital excitations in Ca2RuO4 and their nature, originating from the interplay of spin-orbit coupling and octahedral rotations: nature.com/articles/s4200…

🗣️Today you could hear Leonardo at @unige_en giving a talk on invitation of Prof. Louk Redemaker's group! Leo was talking about RIXS and electron phonon coupling 😊

We’re attending the Superconductivity @GordonConf on the Role of Topology, Dimensionality, and Correlations in Unconventional Superconductivity😊 Come meet Leo, who is presenting a poster on the effect of uniaxial strain on dynamic charge correlations in superconductors!

The first day of our group retreat 🥰 we started with a lovely walk around Chur and then we continued with talks

Conference alert ‼️ Jens was representing us at the DESY @desynews Photon Science Users' Meeting in #Hamburg with two talks about: 🗣️ Denoising x-ray diffraction images 🗣️ The oxygen superlattice in nickelate #superconductor s

🗣️This week, our group had the pleasure of hosting the Seminar in Condensed Matter Physics with guest speaker, Prof. Neven Barisic form @tu_wien! Neven, thank you for your great talk and for presenting your vision of cuprate superconductivity !👏
