AIP and APS are excited to award Samson Shatashvili with the 2025 Dannie Heineman Prize for Mathematical Physics. Shatashvili is being recognized for his clever use of various techniques in studying symmetry in quantum field theory, particularly his work with L. Faddeev on anomalies, with C. Vafa on exceptional holonomy compactifications of superstrings, and for the co-discovery of Bethe/gauge correspondence between supersymmetric vacua and quantum integrability. This annual award recognizes significant contributions within the field of mathematical physics.

Researchers from Science Tokyo have discovered that bacterial swarms transition from stable vortices to chaotic turbulence through distinct intermediate states. Combining experiments with bacterial swarms, computer simulations, and mathematical modeling, the team clarified the intricate process by which orderly swirling turns to disordered turbulence as the free space available to bacteria increases. These findings provide new insights into active matter physics and could inform future applications in micro-robotics, biosensing, and active fluid-based micro-scale systems.

Susanna Heikkilä solved a problem in topology, or mathematics pertaining to the shape of surfaces. The fact that one of the articles included in her doctoral thesis has been approved for publication in the highly esteemed Annals of Mathematics journal speaks to the exceptional nature of her results.
