Understanding the complex behavior of many-body systems where thousands or even millions of particles interact simultaneously has long been one of the biggest challenges in modern plasma physics and statistical mechanics. How do these countless interactions produce the collective patterns observed in nature? And can artificial intelligence (AI) help scientists uncover physical laws that traditional models cannot fully explain?
A recent study published in Proceedings of the National Academy of Sciences (PNAS) introduces a groundbreaking theoretical approach that combines machine learning, neural networks, and laboratory plasma experiments to explore this question. Researchers from Emory University applied an advanced AI model to analyze interactions inside a dusty plasma, a form of ionized gas containing charged microparticles. Their goal was not simply to process data but to reveal new physics governing particle interactions in complex systems.
Unlike many scientific applications of AI that focus on prediction or pattern recognition, this research uses a physics-informed neural network to identify hidden principles behind non-reciprocal forces—interactions where forces between particles are not equal and opposite. These asymmetric forces strongly influence the behavior of plasma and other many-body systems.
According to Justin Burton, an experimental physicist at Emory University and senior co-author of the study, the results demonstrate that AI can do more than analyze experimental data. It can actually help scientists discover new physical laws. Importantly, the researchers emphasize that their AI model is not a “black box.” Instead, it provides a transparent framework that explains how and why the algorithm identifies these physical relationships.
Using precise laboratory measurements from dusty plasma experiments, the AI system revealed previously unseen details about non-reciprocal particle interactions, achieving over 99% accuracy in describing the forces involved. The analysis also showed that some long-standing theoretical assumptions about these forces are incomplete or slightly inaccurate, offering corrections based on highly detailed observational data.
The research team—including theoretical physicist Ilya Nemenman and lead author Wentao Yu—believes this AI-driven framework could transform the study of complex interacting systems across multiple scientific fields. Beyond plasma physics, the same method may help researchers uncover hidden interaction laws in systems such as colloids, active matter, and biological cell clusters.
Supported by organizations including the National Science Foundation and the Simons Foundation, the study highlights how interdisciplinary collaboration between AI and physics is opening new pathways to discovery. By combining machine learning, experimental plasma research, and theoretical modeling, scientists are beginning to uncover deeper insights into how complex systems behave—from laboratory plasmas to living biological structures.

What if the universe’s most common form of matter still hides secrets waiting to be discovered?
Plasma—often called the fourth state of matter—makes up over 99% of the visible universe, yet scientists are still uncovering new physics within it. From stars to lightning, plasma plays a fundamental role in cosmic and terrestrial phenomena.
