Emergent Slow Thinking in LLMs as Inverse Tree Freezing

Researchers present a statistical-physics framework explaining how large language models develop multi-step reasoning through reinforcement learning with verifiable rewards (RLVR), modeling the process as inverse tree freezing in a concept network. They propose Annealed-RLVR, a timing-optimized training method that outperforms standard RLVR by applying supervised fine-tuning at peak frustration rather than after convergence, preventing policy collapse.

A Theory of LLM Information Susceptibility

Researchers propose a theory of LLM information susceptibility that identifies fundamental limits to how large language models can improve optimization in AI agent systems. The study shows that nested, co-scaling architectures may be necessary for open-ended AI self-improvement, providing predictive constraints for AI system design.

Constituency Optimisation Through Hamiltonian Representation Of Mandates (COTHROM): Algorithmic Redistricting of Irish Election Boundaries

Researchers have developed COTHROM, the first computational framework for optimizing Irish electoral redistricting using statistical physics and machine learning algorithms. The system balances multiple constitutional objectives—such as proportional representation and geographic compactness—by treating them as variables in a Hamiltonian function, demonstrating improvements over existing legal boundaries in County Cork.

Interpreting FCDNNs via RG on Exponential Family

Researchers establish a theoretical bridge between renormalization group (RG) methods from statistical physics and deep neural network training, proving that optimal DNN parameters correspond to RG fixed points for exponential family distributions. This work extends prior results from discrete to continuous data, providing mathematical foundation for understanding why deep learning effectively extracts features from real-world datasets.
