# Critical slowing down and error analysis in lattice QCD simulations

@article{Schaefer2011CriticalSD, title={Critical slowing down and error analysis in lattice QCD simulations}, author={Stefan Schaefer and Rainer Sommer and Francesco Virotta}, journal={Nuclear Physics}, year={2011}, volume={845}, pages={93-119} }

Abstract We study the critical slowing down towards the continuum limit of lattice QCD simulations with Hybrid Monte Carlo type algorithms. In particular for the squared topological charge we find it to be very severe with an effective dynamical critical exponent of about 5 in pure gauge theory. We also consider Wilson loops which we can demonstrate to decouple from the modes which slow down the topological charge. Quenched observables are studied and a comparison to simulations of full QCD is… Expand
