So excited to finally announce that I moved to Berlin to lead my own research group "THz Structural Dynamics" at Fritz Haber Institute of the Max Planck Society. Follow our adventures here or at pc.fhi-berlin.mpg.de/tsd/

Looking forward to seeing the amazing work that will come out of the newest group at FHI!

Out now: By developing #2D-OKE #spectroscopy, we finally found a surprisingly unified origin of the variety of Kerr signals in lead halide #perovskites. Spoiler🚨: It’s neither organic cations nor the lattice dynamics! pnas.org/content/118/7/… with XYZ Group at Columbia Chemistry

If you do ultrafast OKE on condensed media read our paper! It's no j-OKE! doi.org/10.1063/5.0037… Fig: Simulated ultrafast OKE signal for CsPbBr3 shows that spectral dispersion and anisotropy lengthens & distorts the instantaneous response from pulse overlap.

Magnetic order of the CrSBr monolayer and bilayer measured using second harmonic generation! 🧲👩🏽‍🔬🤯 pubs.acs.org/doi/full/10.10…

Have you ever worried how anisotropy and dispersion distort your pump-probe signals or might be even mistaken for a coherent response? If not, please do so. We modelled such FWM effects with XYZ Group : aip.scitation.org/doi/10.1063/5.… What's your fav. #SpectroscopyAwareness shtick?

🥳Already 2nd cover this year with XYZ Group. This time at The Journal of Physical Chemistry Letters: Feifan used our novel 2D-OKE technique to demonstrate how optical anisotropy and phase transitions can be tuned in alloyed CsₓMA₁₋ₓPbBr₃ #perovskite single crystals. pubs.acs.org/doi/abs/10.102…

Congratulations to @VPolicht and all co-authors for our last paper on Nano Letters! We have dissected Interlayer Hole and Electron Transfer in 2D Heterostructures via 2DES. Fruit of a great collaboration with XYZ Group! @fisipolimi Politecnico di Milano Columbia University pubs.acs.org/doi/10.1021/ac…

We are real gamers. 😤😎 Our twitch stream allows multiple group members monitor readouts while the sample is annealing. Hope it doesn't melt. 😳 m.twitch.tv/sampletempxyz

If haven’t see it yet check our some of our latest results….

Writing in Science Advances, XYZ Group & colleagues UWChemistry describe exciton-polariton condensates that could serve as quantum simulators of many-body spin-orbit-coupled phenomena in a solid-state, high-temperature model system science.org/doi/10.1126/sc… #ColumbiaQuantum

"Colloquium" is a funny word.

In our last work (Nano Letters), we disentangle Pauli blocking, shift and broadening of 1L-WS2 A exciton after ultrashort photoexcitation on- & off-resonance. Chiara Trovatello 👏🏻 A beautiful collab with TU Berlin Columbia Quantum Initiative XYZ Group @fisipolimi pubs.acs.org/doi/full/10.10…
