Semiclassical Description of Confinement and the Global Structure of Eta

This conference talk by Yuya Tanizaki from the Yukawa Institute for Theoretical Physics (YITP) explores the semiclassical description of confinement and the global structure of eta in strongly interacting Quantum Field Theory. Delve into the complex world of Quantum Chromodynamics (QCD) and Yang-Mills theory, where asymptotic freedom at short distances gives way to strong coupling at long distances, leading to quark confinement and chiral symmetry breaking. Learn how recent developments in Lattice Gauge Theory have transformed it into a precision tool through improved algorithms, theoretical insights, and increased computational power. The presentation is part of a conference co-sponsored by the Simons Collaboration on Confinement and QCD Strings, which aims to stimulate interplay between lattice and continuum approaches to QFT with applications ranging from Euclidean and Hamiltonian approaches to string-theoretic perspectives on confining flux tubes and connections with quantum simulation and computation.
