Excited to share our latest work with Guanming Zhang and @stemartiniani.bsky.social in @natcomms.nature.com, where we uncover universal long-range structure in three distinct noisy particle systems spanning soft matter and machine learning.

Flow maps?
What if a world model could imagine the future from a completely different perspective? Introducing XVWM: given one view and an action, predict the future from another camera. A building block for theory of mind.

New preprint!
So, say you're studying some critical transition. How do you catch its universality? Pair correlations? Boring!
We threw line segments at the system, looked at intersections with clusters, and uncovered static and dynamical universal behavior of MIPS!

New paper just out, as an editor's suggestion in PRL!
While looking for the ideal isotropic bandgap material, we actually discovered new structures.
These structures lie at the border between order and disorder, and that's good for optics!

If everyone does it, it must be right…right? Not quite. In “All That Structure Matches Does Not Glitter” #NeurIPS2025 we show CSP benchmarks miss polymorphs and datasets are duplicated. New deduped data, polymorph-aware splits, METRe & cRMSE. Harder tasks, better models!

Check out our latest paper in collaboration with Mathias Casiulis, Naomi Oppenheimer, and Matan Ben Zion on a simple geometric design rule to achieve robotic swarm intelligence. The paper is out today in the Proceedings of the National Academy of Sciences (PNAS).

Contrastive Self-Supervised Learning is Just Sphere Packing!
CLAMP (Contrastive Learning As Manifold Packing) recasts SSL as neural manifold packing with a physics-inspired repulsive-particle loss (like in jamming) and achieves new SOTA on ImageNet-100. arxiv.org/abs/2506.13717
We show that memory persistence is encoded in gene expression manifolds, not single gene changes. Shadow memory proteins like PKMzeta & KIBRA leave no single-gene signature, but reshape network structure. New from our lab + Hofmann + Fenton lab: www.biorxiv.org/content/10.1...
🚀 Satyam and Guanming’s “Emergent Universal Long Range Structure in Random-Organizing Systems” shows noise correlations create long-range structure, from 🧩 hyperuniform materials to 🤖 ML, and that SGD’s flat minima bias is universal. 👇 arxiv.org/abs/2505.22933 #SoftMatter #ML

Nice!
Do systems where the equations are known but cannot be solved in less than exponential time count? If so just take Schroedinger's equation for an interacting many-body system. Perfect description of the problem with no solution :)
Oh and if you think "but surely hydrodynamics was derived from atomistic theories", think again, a lot of hydrodynamics (e.g. Flick's law) was derived phenomenologically (in neuro language, normatively)
So do we need to know the state of every cell in the brain to know the state of the brain? I hope not! We can only understand and predict with coarse grained theories.
In principle this would work but the size of the system of equations that one would have to solve and the time required to solve them makes it 1/ impossible 2/ a dumb proposition because we have a coarse-grained theory (fluid dynamics and continuum mechanics) which are better suited for this problem
I think more to your point, and not unrelated to my previous example, take the lift of a plane. Someone fixated with microscopic details would argue that to model a plane one would have to run a molecular dynamics simulation of every atom in the plane and the surrounding air.
