Explore a 38-minute conference talk on "Structure and Response in Disparate Universal Regimes" presented by Joe Carlson from Los Alamos National Laboratory. Delve into the fascinating world of few-body physics near unitarity, where the two-body scattering length dominates as the largest length scale. Gain insights into the current status of this field, examining its applications and challenges in atomic and nuclear physics. Discover the intriguing connections between these vastly different scales, including the three-body Efimov effect. Recorded as part of the "Opportunities and Challenges in Few-Body Physics: Unitarity and Beyond" conference at the Kavli Institute for Theoretical Physics, this talk promotes cross-disciplinary exchange between theory and experiment across various physics domains. Uncover the unifying principles of universality that link diverse areas such as nuclear, atomic, molecular, condensed matter, high-energy, and mathematical physics.
