Mathematical physics sits at the fascinating intersection where abstract equations meet the fundamental laws of our universe. This field uses rigorous mathematical tools to model everything from the behavior of subatomic particles to the curvature of spacetime, turning complex theories into testable predictions. It is the language through which physicists describe reality, bridging the gap between pure mathematics and physical observation.

On Gist.Science, we process every new preprint published in this category on arXiv to make these dense studies accessible to everyone. Whether you are a specialist or a curious reader, you will find both plain-language overviews and detailed technical summaries for each paper. Below are the latest mathematical physics papers from arXiv, curated to help you explore the cutting edge of theoretical science.

Causal Architecture in Hidden Quantum Markov Models

This paper introduces causal hidden quantum Markov models (cHQMMs) where emissions precede hidden state transitions, demonstrating that this causal order generally produces distinct, distinguishable quantum processes compared to conventional models, while proving that the two architectures converge only when derived from entangled liftings of classical hidden Markov models, thereby establishing a clear boundary between classical and genuine quantum memory effects.
