New preprint from our team: arxiv.org/abs/2409.04372

A new algorithm for computing #material properties in #densityfunctionaltheory (#dft) based on inexact #krylov methods: we safe 40% computational cost by an adaptive selection of convergence tolerances inspired from #mathematical analysis.

arXiv.orgKohn-Sham inversion with mathematical guaranteesWe use an exact Moreau-Yosida regularized formulation to obtain the exchange-correlation potential for periodic systems. We reveal a profound connection between rigorous mathematical principles and efficient numerical implementation, which marks the first computation of a Moreau-Yosida-based inversion for physical systems. We develop a mathematically rigorous inversion algorithm which is demonstrated for representative bulk materials, specifically bulk silicon, gallium arsenide, and potassium chloride. Our inversion algorithm allows the construction of rigorous error bounds that we are able to verify numerically. This unlocks a new pathway to analyze Kohn-Sham inversion methods, which we expect in turn to foster mathematical approaches for developing approximate functionals.

The author of the "Material Theme" and "Material Icon Theme" for Visual Studio Code, has just pulled the dirtiest move I've ever seen from an extension developer.

With the latest "update" they pulled all previous versions, changed the name & licence, blocked all feedback/comments and made the theme "paid".

It's since been reviewed-bombed from nearly 5, to barely 1.5 stars, but after it been FOSS for a decade and as one of, if not the most popular theme pack, I'm unsure what else they expected.

note（ノート）核融合原子炉｜ポイズン雷花核融合技術は未来のエネルギーとして期待されてます。 放射性廃棄物が出ない理想的なエネルギーとも云われますが、果たして本当なのでしょうか？ もうご存じの方も居られますと思いますが、核芬利原子炉では長期に渡り、強い放射線にさらされる事で素材その物の性質が変化して炉事態が放射性に成る現象が起こります。科学的には未だ解明されていない様だ。従って、融合原子炉でも同様の現象が発生する可能性は否定出来ません。正確な原因が解らない以上、起き得ないと結論付けるのは無責任でしかない。 確かに使用済み核燃料は発生しませんが、解体の際に炉自体が放射性廃棄物に成る可能性は排除出来ません。 もし放射性廃棄物が出な

note（ノート）Реактор ядерного синтезу｜ポイズン雷花Очікується, що технологія ядерного синтезу стане енергією майбутнього. Кажуть, що це ідеальне джерело енергії, яке не виробляє радіоактивних відходів, але чи це правда? Як деякі з вас, можливо, вже знають, коли реактор на ядерному паливі піддається сильному випромінюванню протягом тривалого пері
