Description
Despite the intrinsic ambiguity in defining the topological index $Q$ on a discrete lattice, fermionic definitions based on either the Hermitian or non-Hermitian Wilson–Dirac operator yield an integer-valued topological index for any lattice QCD configuration. Here, we focus on configurations in which the topological index changes during the Hybrid Monte Carlo evolution, and investigate the properties of the Dirac eigenmodes that are directly responsible for these changes in $Q$.
