We observe anomalous charge modulations near surface impurities. This local symmetry-broken phase appears to arise from a subtle interplay between non-local impurity potentials, quantum geometry, and enhanced local correlations.

Yesterday Shamarita presented a poster about Aharonov-Bohm caging in classical photonic simulators through Floquet engineering — her master work from TU Kaiserslautern — in the 2nd DPG Fall Meeting in Göttingen.

Welcome our new group member Lichen Ji, who recently got her PhD at Tsinghua University studying superconducting proximity effect. She joined us this month as a postdoc (shared with TQC Thin Films group) and she will explore chiral superconductors with molecular beam epitaxy.

Here we go again! Time lapse of touchdown and assembly.

All boxes are open, and the cryogenic dewar is mounted on the vibration isolation table. Now comes the real heavy lifting — time to settle the system into the pit!

(30 Jun) Today Dongming Zhao, our new postdoc who joined us earlier this month, gave an excellent introduction talk in TQC PhD and group seminar about his doctoral thesis on higher-order topological insulators. Welcome Dongming!

(19 Jun) Today’s the big day — our STM has arrived! 🥳
All 7 crates📦are now safely stored in the basement. Huge thanks to everyone involved, and a special shoutout to our technician Ole for making it all run so smoothly.
Unpacking will happen in a couple of weeks — stay tuned!
