Computing the Topological Susceptibility from Fixed Topology QCD Simulations
The topological susceptibility is an important quantity in QCD, which can be computed using lattice methods.However, at a fine lattice spacing, or when using high quality chirally symmetric quarks, algorithms which proceed in small update steps -in particular the HMC algorithm -tend to get stuck in a single topological sector.In …
