Self-Dual Monopole Loops, Instantons and Confinement

Explore the intricate connections between self-dual monopole loops, instantons, and confinement mechanisms in quantum chromodynamics through this 57-minute conference talk delivered at the 2025 Simons Collaboration on Confinement and QCD Strings Annual Meeting. Delve into advanced theoretical physics concepts as the speaker examines how self-dual monopole configurations relate to instanton solutions and their role in understanding confinement phenomena in gauge theories. Investigate the mathematical frameworks underlying these topological objects and their significance in non-Abelian gauge theories, particularly focusing on how monopole loops contribute to the confinement of quarks and gluons. Analyze the interplay between these different topological structures and their collective impact on the vacuum structure of QCD, gaining insights into one of the most fundamental problems in theoretical physics regarding the mechanism behind color confinement.
