  1. `Hirshfeld atom refinement (HAR) has begun to emerge as an alternative, potentially more accessible, quantum crystallography approach for experimentally visualizing covalency, but it has remained limited and technically impracticable regarding heavy element complexes... Here, we apply HAR to two extreme test cases of clusters containing three proximate heavy actinides exhibiting multi-center thorium-thorium bonding.`

  3. China's LineShine Supercomputer: A Sense of Scale ⚡🖥️

    China's LineShine 灵晟 supercomputer is the most powerful supercomputer in the world 🌍, delivering a verified 2.198 exaFLOPS on the TOP500 benchmark. That means it can perform more than 2 quintillion (2×10¹⁸) calculations every second 🚀. The system consumes 42.2 megawatts of electricity ⚡ and is powered by more than 13.7 million conventional CPU cores 🧠.

    The Scale of Its Computing Power 📊

    Compared to Humanity 👥: If every person on Earth performed one mathematical calculation every second, without stopping ⏱️, it would take the entire global population about 4 years 📅 to equal the amount of computation LineShine completes in a single second.

    Consumer Hardware 💻: Matching LineShine's sustained performance would require more than 20 million of today's fastest consumer graphics cards 🖥️, such as an RTX 5090, working together in perfect synchronization 🔗.

    LineShine demonstrates the extraordinary scale of modern high-performance computing (HPC), enabling scientific calculations that would be practically impossible using conventional computers 🚀.

  16. `In this paper, we show a quantum simulator system that consists of a continuously driven Kerr parametric oscillator with a third-order nonlinearity that can be operated in the quantum regime to create a fully tunable asymmetric double-well. Our experiment leverages a low-noise, all-microwave control system with a high-efficiency readout, based on a tunnel Josephson junction circuit, of the which-well information.`

  18. Molecular Physics Early Career Researcher Prize 2024 — the official profile article is now out! 🎉

    The awarded paper focused on advanced quantum-chemical calculations for predicting bond lengths and vibrational frequencies — well outside my primary field of medicinal chemistry. I’m grateful this work has been recognised internationally. 💪

  20. New preprint arxiv.org/abs/2511.06957

    A #perspective discussing Moreau-Yosida (MY) techniques in #densityfunctionaltheory.
    MY regularisation has enabled to import tools from #convexanalysis into #dft
    providing a new mathematical understanding of the most important atomistic simulation approach
    and new robust algorithms for Kohn-Sham #dft.

    Thanks to my co-authors from the #hylleraas centre and #oslomet for insightful discussions.

  28. Question for @jimalkhalili and @sellathechemist ...

    @VergaraLautaro is looking to read a book or two which tells the story of how the advent of quantum mechanics impacted Chemistry. Specifically, how did the theory of orbitals and filling rules develop, what experiments confirmed them, and when. When and how were covalent and ionic bonds understood, etc. All of that.

    Jim, I know you had a section on the influence of Quantum Physics on living systems, and Andrea, I know your work is likely to require significant knowledge of these things.

    Can you point @VergaraLautaro in the right direction?

    OK, HashTags

    #RussiaIsATerroristState and a dying country because the #Soviet official rejection of *both* the revolutionary #genetics 🧬 and #QuantumChemistry developments in ‘the West’ resulted in a #BrainDrain in #biology and #chemistry that they will *never* recover from.

    And they clearly don’t know ‘the First Rule of Holes’ (Stop digging when you’re in one 🕳️) because now they’re putting their top physicists in gulags, too! bbc.com/news/articles/c8001gvp

  34. @mariapopova I believe you correctly surmise “how staggered (Emily Dickinson’s) pliant young mind must have been to learn that scientists had just proven the existence of atoms.”

    But #physicists didn’t accept the #AtomicTheory until #AlbertEinstein demonstrated its verity through Brownian motion over a *century* after #JohnDalton proposed it.

    Both ‘particle #chemistry ‘ and #QuantumChemistry predate their #physics counterparts by a century since Dalton quantized *mass*!
