The DIRAC26 source code is available from ZENODO at zenodo.org/records/186620… !

DIRAC26 is out, Check out diracprogram.org/doku.php?id=fe… for a list of new features, enhancements, optimizations and bug fixes of DIRAC26 compared to DIRAC25.

Catching up on the science behind the quantum advantage announcement by Google. Nice to have heard the story behind arxiv.org/abs/2510.19550 first hand from Tom O'Brien.

This plan is absurd, but brutality sadly rules in much of the world. Hope this petition may help: oppose the layoff of the NIST Atomic Spectroscopy Group - Sign the Petition! chng.it/BCy5DKJmJT via @Change

DIRAC25 is released today. Check out diracprogram.org/doc/release-25/ for the new features and download information.

Hiroshima, Japan was just selected to be the location of REHE2026.

The second REHE to take place in NL is about to start, looking forward to meet old friends and make new ones in Amersfoort: rehe2024.nl

[2410.03620] Time-Reversal Symmetry in RDMFT and pCCD with Complex-Valued Orbitals #compchem arxiv.org/abs/2410.03620

Looking back at productive tensor.sciencesconf.org. Thanks to all the participants to make this a success, hope we can keep the momentum.

A full list of features, enhancements, optimizations, and bug fixes of DIRAC24 compared to DIRAC23 is found here: diracprogram.org/doku.php?id=fe… #compchem #theochem #HPC #openscience

The 2024 version of DIRAC is now officially released. Hop over to diracprogram.org to download your copy.

And the day before defending his thesis also the linear response appears: pubs.acs.org/doi/full/10.10…

Quadratic response can be faster than linear response, at least when it concerns published papers, Xiang Yuan's nice work on QR is now online: pubs.acs.org/doi/10.1021/ac…, while we still need to refer you to the arxiv for equally nice work on linear response.

The 14th REHE conference (NL, October 7 to October 11, 2024) is taking shape, stay tuned at rehe2024.nl for the latest news.

Well deserved honor for Arno Förster: hrsmc.nl/shared-content…

SCM is proud to announce that it is one of the winners of the “Quantum SME” call! 🙌 Click here for more info on the project, which is sponsored by @QuantumDeltaNL: scm.com/news/embedding…

Intensive discussions at the annual @DIRACprogram meeting, especially on parallel GPU-adapted tensor operation libraries for #coupled_cluster work. Looking to team up with other groups to define #standards for #tensor_operations. BLAS4 ? @aspgpp @janbrandejs
