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

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💪

[Laboratory for Quantum Matter Research @JohanChangLab]

We are at SCES 2025 !

Two contributed talks checked ✅

Best greetings from Montréal from Iza & Leo 👋

🗣️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 😊

[Laboratory for Quantum Matter Research @JohanChangLab]

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:

[Physical Review Letters @PhysRevLett]

A signal similar to that produced by the anomalous Hall effect arises in topological materials, but without also exhibiting spontaneous time-reversal symmetry breaking https://t.co/Wfv72E92No

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!

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

[Laboratory for Quantum Matter Research @JohanChangLab]

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

[Laboratory for Quantum Matter Research @JohanChangLab]

🗣️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 !👏
