Physicist. Imagining brave new worlds. When not exploring 2D/topological materials, I like writing/travel, capture that fleeting moment or enjoy the best coffee

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. 🧵

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

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

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

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.

Sam Altman talks about GPT-8 with David Deutsch, one of the world's most brilliant physicists
Sam asks him if GPT8 solved quantum gravity, would that convince him that AGI is achieved.
David Deutsch argues the Turing Test is no real measure, LLMs, even "GPT-8" lack true creative inspiration, and AGI won’t fit into fixed-test evaluations.
But if GPT8 can solve quantum gravity that would be AGI for him.

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.

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).

Generative AI owes part of its success to a peculiar physical material that was once thought to be useless.
