@foatorres How comes so? 😯

A simulation that refused to match its own analytical solution. Not a typo. Not a bug. We stripped the problem down to a 2×2 matrix (gain, loss, and a precision floor) and the mismatch sharpened. The irreversibility was coming from the arithmetic itself. 🧵

As Borges said: "Pensar es olvidar diferencias" — to think is to forget a difference. Finite dynamic range enforces this forgetting. And what physics cannot distinguish, it cannot reverse. arxiv.org/abs/2603.22284

Today on arxiv: "Precision's arrow of time." We derive when reversibility breaks, verify it across arbitrary-precision and hardware arithmetic, and propose experiments in photonics and electrical circuits. With G. Pappas, V. Achilleos & D. Bautista Avilés. arxiv.org/abs/2603.22284

Our colleague Diana Dulić passed away recently. We are remembering her today at the FCFM dfi.uchile.cl/noticias/23731…

@raizamrtn I've used @gethuxe since day one and it's transformed my morning commute. Audio-only and non-invasive—I get pending emails, calendar conflicts, and personalized news while walking or on the subway. It genuinely turbocharges my day. Thanks for building this!

When we launched Huxe in September, I knew we were on to something special. It’s a simple enough idea: what if AI could go first? What would it take to make something really thoughtful, made especially for you? No prompts (or screen) needed - just a carefully curated list of bite sized podcasts you could listen to that were thought provoking, interesting, useful. Thanks to our thousands of users (and everyone in the Discord), in the last month we’ve learned a lot about what people want from personalized AI - particularly audio - and we’re excited to share a ton of updates today that make the app even better. Here are some of the highlights:

Our latest research is out in @NanoLetters! Congrats and thanks to @earodriguezmena and @mberdakin for all the work behind this. @ACSPublications pubs.acs.org/doi/full/10.10…

Dear Colleague, We are thrilled to invite you to GRAPHENE 2026 - the 16th edition of the Graphene Conference series and the premier European event on graphene & 2D materials, to be held June 30 – July 3, 2026, in Barcelona, Spain grapheneconf.com/2026/

Tomorrow's Nobel may be among the last where humans did all the work. This interview points to an imminent future: prizes awarded to human-AI teams, and Nobel-worth AI discoveries that redefine scientific achievement—prize or not.

Researchers extend the Středa formula to periodically driven systems, offering a new way to express #FloquetSystem #topological invariants and providing a physically grounded link between Floquet winding numbers and tractable response functions. 🔗 go.aps.org/4gel8OK

"𝘈 𝘯𝘰𝘯-𝘩𝘦𝘳𝘮𝘪𝘵𝘪𝘢𝘯 𝘭𝘰𝘰𝘱 𝘧𝘰𝘳 𝘢 𝘲𝘶𝘢𝘯𝘵𝘶𝘮 𝘮𝘦𝘢𝘴𝘶𝘳𝘦𝘮𝘦𝘯𝘵" is finally published! @StephanSroche iopscience.iop.org/article/10.108…

and this is a podcast (created using @NotebookLM) on two of the articles of this Quanta Magazine issue ("The Strange Physics That Gave Birth to AI" and "Where Do Scientists Think This Is All Going?"): notebooklm.google.com/notebook/ea2f0…

Read "The Strange Physics That Gave Birth to AI" for a nice example of how we cannot untie the applied (most often thought of as useful) from the basic science (Physics in this case).

Our latest paper is out! @PhysRevResearch
