We look back fondly on the SPS-ÖPG meeting in beautiful Vienna😊 See you next year!
PRB Editors' Suggestion: Decoupling of static and dynamic charge correlations revealed by uniaxial strain in a #cuprate #superconductor L. Martinelli et al. PRB 112, L041124 ➡️ go.aps.org/4ffbURH #PRBLetter #OpenAccess #EdSugg @APSphysics #physics #condmat @JohanChangLab
🌟Chech our new @arxiv @arxiv_articles by I. Biało et al., about the first Tl-based Mott insulating cuprate ! ⬇️ arxiv.org/abs/2507.22242
💡Check out our new @arxiv @arxiv_articles about charge ordering in Pr-YBCO superconductor: ➡️arxiv.org/abs/2507.20640
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!
Editors' suggestion in @PhysRevLett @APSphysics 💪 See our new paper about Weyl semimetals:

Our second time at BESSY in the last three months 💞 This time, we're calibrating one of our uniaxial strain devices 💪 As always, many thanks to Eugen!
❗️@arxiv @arxiv_articles alert ❗️ 'Observation of collective charge excitations in a cuprate superconductor' -thorough RIXS-based phonon analysis + phonon simulations presented by our PhD student, Xunyang ⬇️ arxiv.org/abs/2503.04334
Check out our new banner photo😍⬆️ Greetings from beautiful Arosa #switzerland from: at the top left - Ola, Johan, Sophie, Xunyang, Leo at the bottom left - Patrick, Wojtek, Jens, Lorentzo, Iza
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 !👏
Today @JohanChangLab help supervise the exam for medical and veterinary students in the course led by Johan at @UZHPhysics good luck to all candidates 🤞
🤩Our nickelates studies published in @CommsMaterials @SpringerNature ! Check out the the giant unit-cell oxygen superstructure in infinite layer nickelates👇 nature.com/articles/s4324…
We began the New Year by attending the 2nd Workshop on Muon Science, Technology, and Industry at the China Spallation Neutron Source (CSNS). Johan presented our μSR studies conducted in collab with Prof. Shu. We look forward to visiting the upcoming μSR facility at CSNS: MELODY🎶
