Many-body Systems Demonstrate New Correspondences, Solving Complicated Problems Via Gauge Theories
Summarize this article with:
The surprising connections between seemingly disparate areas of physics, specifically gauge theories and many-body systems, form the focus of new work by Igor Chaban of Columbia University, Nikita Nekrasov from Stony Brook University and the Simons Center for Geometry and Physics. These researchers explore two distinct but related correspondences that bridge the gap between these fields, revealing deep mathematical relationships previously understood only in limited contexts. Their investigations build upon earlier work from the 1980s and 1990s, utilising techniques like Hamiltonian reduction to demonstrate how parameters defining a gauge theory can directly correspond to those of a many-body system. Furthermore, they examine a duality emerging in the mid-1990s, which transforms complex problems into simpler, solvable forms, offering a powerful new approach to understanding both classical and quantum systems and promising advances in areas ranging from particle physics to condensed matter physics. Integrable Systems, Quantum Field Theory, and String Theory Research in several areas of theoretical physics, including integrable systems, quantum field theory, and string theory, shares common mathematical foundations. Investigations reveal connections between these fields, encompassing topics such as soliton equations, supersymmetric gauge theories, and representation theory, as well as areas of algebraic geometry and symplectic geometry. This work demonstrates the interconnectedness of these seemingly disparate branches of physics and mathematics. Studies of integrable systems have focused on areas like Calogero-Moser systems and action-angle maps, providing insights into their mathematical structure and scattering theory. Simultaneously, quantum field theory research has explored topics including Seiberg-Witten theory, topological quantum field theory, and localization techniques, advancing understanding of supersymmetric gauge theories. These investigations often involve sophisticated mathematical tools and techniques. Further research delves into representation theory, examining symmetric groups and representations of Lie groups, alongside algebraic geometry and combinatorics, focusing on Hilbert schemes and quantum cohomology. These areas contribute to a broader understanding of the mathematical structures underlying physical theories, offering new avenues for exploration and potential applications. Gauge Theories and Integrable Systems Linked This work establishes connections between gauge theories and integrable systems, revealing a deep relationship in their underlying mathematical structures. Researchers have demonstrated how parameters defining gauge theories align with those of integrable systems through Hamiltonian reduction, building on earlier work from the 1980s and 1990s. This correspondence provides new perspectives on both fields and facilitates cross-disciplinary insights.
The team also investigated a duality, originating in the mid-1990s, that links classical problems to their counterparts in different mathematical frameworks, including Fourier and Legendre transforms, and Langlands duality. This duality simplifies complex calculations by enabling solutions from one area to inform challenges in another, offering a powerful approach to theoretical physics. While the current analysis focuses on specific systems, the authors suggest that extending these correspondences to more general cases represents a promising direction for future research. 👉 More information 🗞 Lectures on Gauge theories and Many-Body systems 🧠 ArXiv: https://arxiv.org/abs/2512.23099 Tags: Rohail T.
