Meet us at #STC2026 in Graz!

We’re looking forward to seeing familiar faces and welcoming new members to the #ORCA family. Stop by our booth to talk with the team about ORCA, our Python interface #OPI, and your research.

See you in Graz!

New preprint: Spin-unrestricted linear-scaling double-hybrid #DFT! Here, authors generalize their earlier linear-scaling MP2 implementation to the spin-unrestricted case, enabling asymptotically linear-scaling DH-DFT for open shell and reactive molecules. doi.org/10.26434/che...
