Semiclassical Limits of Impurities and Wilson Lines - Gabriel Cuomo

Explore the semiclassical limits of impurities and Wilson lines in a 37-minute conference talk from the Confinement, Flux Tubes, and Large N KITP conference. Delve into color confinement, a fundamental phenomenon in physics, and its relation to non-Abelian gauge theories and asymptotic freedom. Examine the formation of chromoelectric flux tubes as a mechanism for confinement, their observation in lattice simulations, and their appearance in gravity duals of confining gauge theories. Investigate the large N limit of gauge theories and its implications for studying the confining string. Cover topics such as perturbation theory in free bulk, partition functions at large s, semiclassical approaches, DQFT methods for impurities and Wilson lines, and applications to 1/2 BPS lines in N=2 theories. Gain insights from experts in color confinement, string theory, lattice gauge theory, gauge/gravity duality, large N methods, and integrability as they combine perspectives on this classic problem in fundamental physics.
