Excited to share our article on recent advances in TURBOMOLE for periodic & molecular DFT! #compchemsky

Special milestone: some of the final results from my PhD are now published + my 10th paper
Grateful to Prof. Marek Sierka & amazing collaborators for the oppurtunity!

Hi #compchem,
Now calculate vibrational modes of a molecule using machine learning interatomic potentials (MLIPs) such as UMA (OMol), MACE OMAT-0, MatterSim, 7Net and many more on MLIP Playground (huggingface.co/spaces/Manas...)
and yes there is a dark mode

but haven't checked the performance for different charges though so can't say about that

So will DFT lmao🤣
You need to find the spin that gives the lowest energy, just like DFT. What I will agree with though is that for compounds out of the training set it may not give the correct spin for the ground state.

What I like the most about the UMA (OMol25) model is that it can take spin and charge as the input. This is a game changer as it allows simulating a large vareity of compounds with correct spin multiplicity. Seems to be quite accurate uptil now in my tests.

Kudos to the entire team on this herculean task!

PySCF users, you're gonna love this! 🎉
CrysX-3D Viewer v1.9.6 now lets you generate PySCF input files (python scripts) for both molecules and periodic systems—instantly from any given chemical structure. Truly a time saver.
Update now 👇

Hi #compchem and #compchemsky community,

My cross-platform application, CrysX-3D Viewer, can now directly visualise a material in the materials project database given its material id such as `mp-149`.
Download the v1.9.5 now👇

Recently, MetaAI released the OMol25 dataset and the UMA model — a powerful foundation model for #compchem community.

Now, you can try UMA and 16+ other MLIPs (incl. MACE) on your own systems with an app that I developed: MLIP Playground👇👇

New group preprint out on ChemRxiv, just in time for the Christmas break, in which Eimear reports the effect of alkyl termination on the optical and electronic properties of silicon nanoparticles, studied using a combination of (TD-)DFT and GW-BSE doi.org/10.26434/che... #chemsky #compchem
TOC figure for the preprint showing how the optical gap of silicon nanoparticles changes with surface termination and particle size
