Thank you very much indeed @rociomer.bsky.social and @smnlssn.bsky.social for the opportunity to visit Chalmers, and to speak in this series! #compchem

🎓 Applications are open for the IMAT Centre for Doctoral Training at @oxfordchemistry.bsky.social & @oxfordmaterials.bsky.social!

Among many exciting topics, have a look at our projects P10 and P13, both combining MLIPs and #compchem with close experimental collaborations: imatcdt.chem.ox.ac.uk

Congratulations Kim!! 🙂

🚨 #machinelearning for #compchem goodies from our 🧑‍🚀 team incoming! After years of work it's time to share. Go check arxiv.org/abs/2508.15704 and/or metatensor.org to learn about #metatensor and #metatomic. What they are, what they do, why you should use them for all of your atomistic ML projects 🔍.

An automated framework for exploring and learning potential-energy surfaces - Nature Communications Machine learning is revolutionising materials modelling but requires high-quality training data. Here, the authors introduce autoplex, an open framework automating exploration and fitting of potential...

🚀 After two+ years of intense research, we’re thrilled to introduce Skala — a scalable deep learning density functional that hits chemical accuracy on atomization energies and matches hybrid-level accuracy on main group chemistry — all at the cost of semi-local DFT ⚛️🔥🧪🧬

🎉 DFT-accurate, with built-in uncertainty quantification, providing chemical shielding anisotropy - ShiftML3.0 has it all! Building on a successful @nccr-marvel.bsky.social-funded collaboration with LRM🧲⚛️, it just landed on the arXiv arxiv.org/html/2506.13... and on pypi pypi.org/project/shif...

Distillation of atomistic foundation models across architectures and chemical domains Machine-learned interatomic potentials have transformed computational research in the physical sciences. Recent atomistic `foundation' models have changed the field yet again: trained on many differen...

Distilling atomistic foundation models! ⚗️🧪🤖 In this #compchem preprint, we describe a general (“architecture-agnostic”) approach to creating fast, application-specific MLIP models via synthetic data – led jointly by @jla-gardner.bsky.social & @dft-dutoit.bsky.social arxiv.org/abs/2506.10956

It is very fast! (In particular for those cases where we need hundreds of thousands of atoms and more – "realistic" polycrystalline samples are one example)

Machine-learning-driven modelling of amorphous and polycrystalline BaZrS$_{3}$ The chalcogenide perovskite material BaZrS$_{3}$ is of growing interest for emerging thin-film photovoltaics. Here we show how machine-learning-driven modelling can be used to describe the material's ...

BaZrS3 is an emerging solar-cell material ☀️ In a preprint led by @biancapasca.bsky.social, we describe an ML potential that can tackle the structural complexity of amorphous and polycrystalline BaZrS3. Very happy to see this online! Read more at arxiv.org/abs/2506.01517
