  2. Systems approach thresholds. Then they reorganize—or collapse. This paper formalizes saturation dynamics across scales: the core recursion equation, boundary functions, and the Recursive Saturation Index (RSI).

  3. We are pleased to announce a second lecture from Dr. Marcello Dalmonte (ICTP) on the intricacies of statistical mechanics and phase transitions in the context of data mining the many-body problem. In this part, Marcello discusses essential concepts of the partition function, emphasizing efficient sampling strategies via Markov chains and Monte Carlo simulations. He specifically addresses the challenge of critical slowing down near phase transitions and introduces cluster algorithms as a powerful tool for effective sampling at criticality. Using the illustrative example of a three-site Ising model, Dr. Dalmonte demonstrates how temperature impacts the intrinsic dimensionality of feature spaces, providing valuable insights into many-body systems.

    🎥 Don't miss this #OpenAccess opportunity to watch the lecture for free and engage in discussions with the Enabla community, including Marcello himself: enabla.com/pub/325/about

    The first lecture of the same series was announced earlier: mathstodon.xyz/@enabla/1131633

  8. "All of this makes phase transitions interesting. They involve violence, universal truths and competition between rival states. The story of phase transitions is, quite literally, the song of fire and ice."

    poetic.

  12. Since we're having a fresh start over here on #ScienceMastodon, I want to share a few things I made a while back with the new audience.

    Let's start with my beginner's guide to #RenormalisationGroup (or #RenormalizationGroup for the American audience!).

    This is a really powerful method in #TheoreticalPhysics and #CondensedMatter is particular. It's used to detect #PhaseTransitions and understand the universal properties of #ComplexSystems. Here's how it works: steventhomson.co.uk/post/rg_gu

  16. Some simplified pictures of physics turn out to be quite effective.

    "Here’s the story of how a toy model of magnetism demystified phase transitions, became ubiquitous in science and continues to help push the boundaries of knowledge today."
