Grayscale screenshots from my generative visualisation tool, exhibiting self-organisation into clusters that resemble lichens and bacterial colonies.

I tweaked the #Ising model in my visualisation tool to operate with continuous rather than binary values. This produces the XY-model (https://en.wikipedia.org/wiki/Classical_XY_model used among other things for simulating defects in liquid crystals.

Pivotal CLTs for Pseudolikelihood in Dependent Random Fields

New pivotal CLTs prove that maximum pseudolikelihood estimators are asymptotically normal for both sparse and dense dependent fields, covering Ising models and exponential random graph models. Read more: getnews.me/pivotal-clts-for-pseudol... #clt #ising

New Algorithms Certify and Learn Quantum Ising Hamiltonians

New algorithms certify Ising Hamiltonians with ~O(1/ε) time‑evolution, matching the Ω(1/ε) lower bound, and learn Gibbs states in trace norm. They also extend to any k‑local Hamiltonian. getnews.me/new-algorithms-certify-a... #ising #quantum

Local order controls the onset of oscillations in the nonreciprocal Ising model We elucidate the generic bifurcation behavior of local and global order in the nonreciprocal Ising model evolving under Glauber dynamics. We show that a critical magnitude of nearest-neighbor correlat...

📢 Exciting research alert! The #Ising model is a fundamental model in statistical physics. We wondered what happened when two sets of Ising models are coupled in a non-reciprocal manner, akin to predator-prey dynamics. The results can be found here 📑 journals.aps.org/pre/abstract...

I can talk, sing and perform in front of anyone at any time. That is the blessing of being a creative entertainer. I was born for this. I never, ever take that for granted.
