Instanton Density Operator in Lattice QCD from Higher Category Theory

This conference talk explores the application of higher category theory to define instanton density operators in lattice Quantum Chromodynamics (QCD). Jing Yuan Chen from the Institute for Advanced Study at Tsinghua University presents research connecting modern mathematical frameworks with computational approaches to strong nuclear forces. Learn about recent developments in Lattice Gauge Theory that bridge Euclidean and Hamiltonian approaches to quantum field theory, with particular focus on how higher categorical structures can provide new insights into instanton phenomena in QCD. The presentation contributes to the broader discussion of strongly interacting Quantum Field Theory applications, including quark confinement and chiral symmetry breaking, while highlighting connections between lattice and continuum approaches to QFT. Part of a conference co-sponsored by the Simons Collaboration on Confinement and QCD Strings, this talk demonstrates the ongoing dialogue between numerical lattice methods and theoretical advances in understanding fundamental forces.
