Nucleon Wave Functions from QCD Vacuum Topology

Instantons, as topologically nontrivial gauge field configurations, provide a microscopic mechanism for chiral symmetry breaking and the $U_A(1)$ anomaly in QCD. Within the instanton liquid model (ILM), instantons generate multi-fermion interactions governed by their density and size. Using this framework, we develop a...
