Entanglement Bootstrap as a Perspective on Quantum Field Theory

This conference talk by John McGreevy from UCSD explores the Entanglement Bootstrap as a perspective on quantum field theory, delving into the complexities of strongly interacting Quantum Field Theory (QFT) and its applications across physical systems. Learn about Quantum Chromodynamics (QCD), the theory describing the strong nuclear force, which exhibits asymptotic freedom but becomes strongly coupled at long distances—where phenomena like quark confinement and chiral symmetry breaking occur. Discover how Lattice Gauge Theory has evolved into a precision tool through improved algorithms, theoretical insights, and computational advances. The presentation connects lattice and continuum approaches to QFT, covering topics including Euclidean and Hamiltonian approaches to lattice field theory, quantum simulation connections, string-theoretic approaches to confining flux tubes, and recent developments in formal QFT such as generalized symmetries. This 44-minute talk is part of a conference co-sponsored by the Simons Collaboration on Confinement and QCD Strings, coordinated by Aleksey Cherman, Lance Dixon, and Igor Klebanov at the Kavli Institute for Theoretical Physics.
